If I looked at the right pictures in one of your earlier links (title of it including 'recent', I think), I didn't like the second Centaur option pictured because I thought it reminded me rather more of a bishop, at least without looking too carefully.
Perhaps that can be 'solved' if it's possible to include a lot more of the base of a knight, maybe even up to horse neck level, including much thicker 'carved lines' at the spine (maybe certain Staunton sets are that way?), and having the bend of the figurine somehow eliminated could be good.
