Can't promise anything, but we are definately looking into this and already experimenting with some ways to add this hopefully in an uncoming patch.
You'd probably add some sort of penalty for the exchange then? To off-set potential abuse? Like paying XP or gold?
By the way, while you're looking into changes, how about adding a recall skill? (to a town or tower) I've found several ways to get stuck in the scenery and you could give it a cool down period and make it take a while to cast to avoid abuse but it would avoid people getting stuck and being forced to reload their game.
Another thing: the mouse wheel is being unused at the moment which is a bit of a shame. Usually it controls the camera but it doesn't here so you could use it to let the user shift between weapon set-ups? For example, move from ranged weapon to sword? It would be very cool to be able to use the mouse wheel to do this.
