Probably not a good idea for people to start changing usernames. It would cause massive confusion especially if all the posts changed to another user. I don't know what to tell you dude.

i dont think it would cause massive confusion - certainly not with arbitrage with 24 posts - establiashed members could add a note to their sig letting people know who they were
as long as admin didnt mind doing it, i dont see a major problem with it
