the original thought that popped into my head was the creatures that were made from experimenting with magick. kind of like Island of Dr. Moreau. which could make sense in a short run.... but would honestly not give enough to create a whole HAUS worth of people... unless it was some catacyslmic event that caused it... but then it would have to be a newer haus that wouldn't nessicarally have a well defined caste system or much order.
A primal force creating a humanoid animals to defend say a land seems like it COULD be a thing..... ill just insert Gaia here... mother earth...undead are plaging the land so Gaia created these hybrid to fight against them. (at least thats what they are told / belive)
if we based the characters off the trianary system i think it would look something like this
Werebear - Top (def the tankiest of the pack)
Wolfman - right (somewhere between strength and cunning)
Kenku - stealthy and smart (between Magick and Cunning closer to the magick side)
Kolbold - somewhere on the bottom (magick and Cunning probly closer to the cunning side)
wererat / ratmen stealthy and quick ( bottom right - Cunning)
goatmen / Khazra - Left (between Strength and Magick)
Gnoll /Jackalman (yes thundercats) - Right side (Strength and Cunning - closer to the Str side)
rakshasa - Tiger/human - in D&D known to be smart id toss bottom left (magick)
troglodyte D&D - somewhere on the Left (Strength and Magick closer to the Magick)
I don't feel like ANY of these hybrids fits a Middle of the ground area (Like Vampire for Deadhaus) but again this is also going off the Trianary system for deadhaus - and we have already learned that each faction will most likely have their own system... just going off of what we know. changing the Essential to Cunning (dexterity) again i'm not the best at comming up with the whole background things and this is just brainstorming and defently subject to change
so if there are any more ideas for hybrid types or how a system might look from anyone else out there toss it in here cause it COULD be a thing
(EDIT - UPDATE) - although looking at all the different characters i think wolfman is less approprate than the werewolf itself....but again i would like to see something different than the vampire transformation as far as a werewolf would go to diferentiate the two and make them each unique.
