The style Larian has always used is that of offering every skill and letting the player build their own class via the choices they make.
Von_Rotten is right about equipment obstructing any cosmetic choices you make concerning your character in just about any game that cares for some realism. That means that choices of hair, etc. are only really relevant for R-Ping. Demand for that is not exactly high, so I'd put my faith in mods filling that gap.
