>>72012819Pony is a bit harder to mix because any mixing with it messes up the anatomy and comprehension but there is quite a few finetunes of it out now so you could probably mix it with other pony derivatives.

The other good model (More for sfw and risque rather porn like pony) is animagine which has all vtubers (plus whole lot of anime/gacha) built in, so you won't need LoRAs.for them.
