I would in a heartbeat. Hell I have suggested this a couple times before. The same goes for coffee cups, beer steins -etc.... There is also an artist on these forums who does some great work I would love for him to do something for my main toon.
I don't consider this much of a problem. WoW has less customisation and it has figureprints like Spore's, all they really are is armour showcases. It's more about the attachement to your character rather than whether they look like someone elses. It may not be unique, bit it IS yours.
