The Citadel is not what it was, they will take anything these days" (Spoilers Extended)

One of my favorite things to do with the ASOIAF series is to look into the identities of "unnamed characters". I've done this numerous times, for example: Identity of Each of the "She-Wolves of Winterfell" and Fun/Unlikely Theory: The Smiling Knight's Identity.

In this post, I would like to look into the identities of the characters that lazy Leo Tyrell mentions in this quote:

The Citadel is not what it was," complained the blond. "They will take anything these days. Dusky dogs and Dornishmen, pig boys, cripples, cretins, and now a black-clad whale. And here I thought leviathans were grey." A half cape striped in green and gold draped one shoulder. He was very handsome, though his eyes were sly and his mouth cruel. -AFFC, Samwell

We should note most of the characters are in the AFFC, Prologue the Quill & Tankard (fearsomely strong cider) where they drink with Pate before he is "replaced".

The current (Gunthor Hightower among others were previously) non maester members of the Citadel:

• Acolytes: (Leo, Mollander, Pate, Roone, Sam)
• Novices: (Armen, Alleras, Lorcas, Robert Frey)

Out of this group we can easily apply identities to a few of the characters (imo):

Pig Boys = Pate

As the current Pate (likely Jaqen H'ghar) states:

"My thanks." There was something about the pale, soft youth that he misliked, but he did not want to seem discourteous, so he added, "My name's not Slayer, truly. I'm Sam. Samwell Tarly."

"I'm Pate," the other said, "like the pig boy." -AFFC, Samwell V

Dornishmen =Alleras/Sarella

Tell me all you told our Dornish sphinx. I know much of it and more, but some small parts may have escaped my notice." -AFFC, Samwell V

Cripples = Mollander

"Here." Dragging his clubfoot, Mollander took a short hop, whirled, and whipped the apple sidearm into the mists that hung above the Honeywine. If not for his foot, he would have been a knight like his father. He had the strength for it in those thick arms and broad shoulders. Far and fast the apple flew . . . -AFFC, Prologue

Black-clad whale = Sam

The chest of books had not been near enough to buy passage for four from Braavos to Oldtown. The Cinnamon Wind was shorthanded, however, so Quhuru Mo had agreed that he would take them, provided that they worked their way. When Sam had protested that Maester Aemon was too weak, the boy a babe in arms, and Gilly terrified of the sea, Xhondo only laughed, "Black Sam is big fat man. Black Sam will work for four." -AFFC, Samwell IV

That leaves us with two unidentified monikers:

They will take anything these days. Dusky dogs and Dornishmen, pig boys, cripples, cretins, and now a black-clad whale

We also have two unnamed characters left: Roone and Armen

Sadly we don't get much description of either character:

Roone

"I should like to see a dragon." Roone was the youngest of them, a chunky boy still two years shy of manhood. "I should like that very much." -AFFC, Prologue

Armen

He has a long/thin and point nose:

Armen looked down his nose at Lazy Leo. He had the perfect nose for it, long and thin and pointed. "Archmaester Marwyn believes in many curious things," he said, "but he has no more proof of dragons than Mollander. Just more sailors' stories." -AFFC, Prologue

and he has forged 4 links of his chain:

"You were born too late for dragons, lad," Armen the Acolyte told Roone. Armen wore a leather thong about his neck, strung with links of pewter, tin, lead, and copper, and like most acolytes he seemed to believe that novices had turnips growing from their shoulders in place of heads. "The last one perished during the reign of King Aegon the Third." -AFFC, Prologue

With the above info in mind I think we can establish:

Cretins = Roone

Keep in mind that Leo is an acolyte:

"You were born too late for dragons, lad," Armen the Acolyte told Roone. Armen wore a leather thong about his neck, strung with links of pewter, tin, lead, and copper, and like most acolytes he seemed to believe that novices had turnips growing from their shoulders in place of heads. "The last one perished during the reign of King Aegon the Third." -AFFC, Prologue

and then we get this response from Leo to Roone:

"Three?" said Roone, astonished.

Leo patted his hand. "More than two and less than four. I would not try for my golden link just yet if I were you."

"You leave him be," warned Mollander. -AFFC, Prologue

But that just leaves us with:

Dusky dogs = Armen Marwyn

I've tried making sense of this and really struggled lol. This honestly the closest I could find for Armen = Dusky Dog:

"The last dragon in Westeros was the last dragon," said Armen doggedly. "That is well known."

LOL

Its more likely that Leo is describing Marwyn here as we get this description of Marwn:

Leo yawned. "The sea is wet, the sun is warm, and the menagerie hates the mastiff."

He has a mocking name for everyone, thought Pate, but he could not deny that Marwyn looked more a mastiff than a maester. As if he wants to bite you. The Mage was not like other maesters. People said that he kept company with whores and hedge wizards, talked with hairy Ibbenese and pitch-black Summer Islanders in their own tongues, and sacrificed to queer gods at the little sailors' temples down by the wharves. Men spoke of seeing him down in the undercity, in rat pits and black brothels, consorting with mummers, singers, sellswords, even beggars. Some even whispered that once he had killed a man with his fists. -AFF, Prologue

So I tend to think this is about Marwyn not fitting the usual description of a maester and the reason that Leo left Armen out, is that is probably because Armen is not only an acolyte (Alleras is too) but also Reachmen can be anti Dornish.

ETA: u/GenghisKazoo raised the potential possibility that Lazy Leo was talking about Alleras with both "dusky dog and dornishmen". Since Alleras is Summer Islander/Dornish and Lazy Leo is a pos, these quotes could lean toward it:

"Truly? Then how would I tell you about the dragons?" Leo shrugged again. "The mongrel has the right of it. The Mad King's daughter is alive, and she's hatched herself three dragons." -AFFC, Prologue

and:

Leo's eyes were hazel, bright with wine and malice. "Your mother was a monkey from the Summer Isles. The Dornish will fuck anything with a hole between its legs. Meaning no offense. You may be brown as a nut, but at least you bathe. Unlike our spotted pig boy." He waved a hand toward Pate.

TLDR: An attempt to look into the identities of who the Citadel is "letting in these days" according to Lazy Leo Tyrell.
