Vanity Exchange

There's been a lot of talk recently about more vanities and cool collectors items that are not really worth it for end-gamers due to low stats. So, I was thinking wouldn't it be a good idea to have the Fallen Prince (or Princess) have a booth (somewhere in Balefort) for players to exchange their items (that are just occupying space) and turn them into instant vanity items.

Some players already pay platinum for random vanity items... It would be a nice feature imho, what do you guys think?
