I think both are a neat idea, though I never thought about creating either of them, mostly because I can't quite wrap my head around combining the anthro and equine anatomies, hahah. But there are some great artists into it already, and I quite enjoy their imagination, especially when it comes to designing produsts and fashion for them.
What about equinoids, but one more step towards human build? With a completely anthro body, with human feet and hands but an equine hear and details does that have a name?
