This probably wouldn't go through, because then players would have to download to play on our servers, and that might make them less popular. However, you could always make them and let people install them for just themselves, if you'd like.
(Also, I'm not sure if its possible to have ~4 different skins on one unit)
Plus, skinning members would give the impression that we think of ourselves to be superior than others, rather than being just like them (i.e. just a player).
