Hello there; Are you familiar with the concept of Equitaur and/or Equinoid?
Equinoid = Equine + Humanoid
Equitaur = Equine/Equinoid + Centaur
An equinoid is basically an anthropomorphic equine with the hooves and hindlegs of said equine's non-anthropomorphic/semi-anthropomorphic counterpart in place on human legs and feet.
An equitaur is basically the centaur(ian) equivalent for an equinoid.
