Is there any hope of getting Yuna's MC2 with crap hones and no RMIIs but decent/somewhat useful relics?

I started out FFRK a month or two ago and have played it semi-casually, so I've really not been at the top of my game. Seeing Yuna's MC2 has left me wanting to go as hardcore as possible until the event ends. I was hoping you guys could help with that. Can you suggest strategies and useful abilities for me to craft and hone until I can even hope to take on the difficulty 110 mission? Based around the characters I've levelled up and gotten relics for?

Yuna - 48 - Lullaby Rod (will get MC1 and egg her up to 60)

Squall - 48 - Cutting Trigger (no MC1)

Penelo - 61 - Judicer's Staff

Tellah - 47 - Polymorph Rod

Tifa - 60 - Platinum Heart (she's an amazing powerhouse with this thing)

Rydia - 61 - Ice Whip (my best Black Mage so far)

Kain - 37 - Blood Lance (can growth egg and break his level cap but afaik this SB is mediocre)

Reno - 60 - Reno's Goggles

Tyro - 30 - Stormlance and Celebration Grimoire

I have Earthmend SB too. Some natural 5* and 3++ armor that should get me through. My X synergy is shit.

My hones are shit. I have Curaga r2 (can hone to r3, probably even 4), -ga BLM fire/ice/lightning spells r2, can craft Curaja but wasn't sure if it was worth it, and crafted Renewing Cure instead (now realising this is useless because Lullaby Rod). Haven't really honed anything else except for the 2 star abilities for the previous quest system. I've crafted Punishing Palm and Tempo Flurry for Tifa, Quake/Darkra/Biora r2, Ruin, Shiva and Ifrit (but given orb conversion I can try and craft the 4 star ones like Maduin), and truthfully, not much else. Got some -Ra spellblade abilities if that's any useful.

So yeah, am I screwed? I'm pretty broke as far as gil goes too. I hover around 100-200k, but can amp it up and farm for it if need be. What strategy could I best employ with those characters and SBs? Which abilities are most useful for Yuna's MC2 specific boss (and the 2 bosses before it, actually) I don't care about ultimate or anything past getting Yuna's MC2, so yeah. Also, as a note, I can go up to difficulty 75 auto-ing the trash in any given dungeon, and having moderately no trouble getting the boss done. However past that I have trouble. I'm not sure what strategy is best with what I have. Anyway jumbled post, but thanks for any help.

this is my stuff in case it's easier

Edit: my abilities Not gonna SS it but I have 2 Retaliates and most characters that can retaliate like Sephiroth (44), Gilgamesh (1) if I remember right, etc but limited eggs
