We'd love to do as many characters from the Bond Universe as possible, but I think we only have 2 or 3 character artists at the moment, and the GoldenEye cast are our priority before other characters can be considered.
I think we could probably do a Q character model that accurately depicts Desmond Llewelyn, since he is dead and I'm fairly certain personality rights in the UK don't trump non-profit artistic depiction after death. It's something worth looking into.
