Doubt I'll be easy or even useful, but I thought if I could met my other character as an NPC. Kinda funny to shipper own chars.
I used to make games (not successfully) and I think a lot about mechanics that I suggest. If it's a cosmetics stuff: it almost have no sense. If you can actually met your char, then you can rob which will make returning less fun (plus there's no gift system, at least yet)
