The Chaos Monogod LHs should be Norsca's Allegience rewards

At its top tier, Norsca's Allegiance to the Gods gives one of four unique characters: 'Killlgore Slaymaim', 'Burplesmirk Spewpit', 'Kihar the Tormentor' and 'Azrik the Maze Keeper'. Some of these characters have been around since the very beginning, but they're still somewhat generic, and they're not names from the Lore or anything.

We're about to reach the point where each Monogod has at least one universally available Legendary Hero. Why not use those as the rewards instead?

I don't think it's a problem if they use DLC lords in a different DLC faction (they've done stuff like that before, for example Thorek gets to use Runelords even if you don't have the King & the Warlord) but if not then they could still give you Karanak & Aekold Hellbrass. We haven't actually had an FLC LH for Slaanesh or Nurgle yet, but there are plenty of options there.

I just think this would be a cool way of using the things we now have in game.
