Appearance changes in-game have been something we wanted to do for a while, but I am unsure of the technical hurdles involved but I know they are not simple and straight-forward. The idea was to return a player to the character creation hall, but that required visiting it while in-game (you actually aren't in-game when you create a character) and locking the other races. I think the mechanism for getting a player back there was also troublesome. Don't know what became of it. Sorry.
