Humantaurs! (Centaur-shaped women with four legs)
Use both high and low models with weight 1.0. Trigger word "humantaur".
If it's not generating the proper number of legs, you might be able to coax it by tweaking your prompt, adding mentions of "four legs", "four feet" and so on.
Variety of poses is somewhat limited. This might be improved in the future as I expand my dataset.
