is it possible to make a minotaur playable character?

as I asked in the title is it, and if it is, would it be extremely difficult?

I ask as I have no idea how to begin adding new races, let alone paperdolls and animations, after some forethought today, I decided I should ask, as I have managed to install weidu, but what other things would I need to do this, and would it be something I could do, as someone who has never even installed through weidu, let alone been able to really understand the underlying mechanics of the game, beyond the 2e rules I know from my childhood.......

I only ask as in 3.5 I play as a Chaotic Good Minotaur who is a Wild Mage.
