I actually do kinda like that title idea, Blue Jay.. Also, yay I was an example!
But naw, haha. I think it is something to consider. I'm not a huge fan of name changes, either. But I'm a little biased. I always use the same two usernames for everything I ever sign up for, and I've been doing it for years. So the names mean a lot to me now, and I'd never consider changing them.
On the staff side, Diana is right that it does create some problems and confusions that could easily be avoided. Although mules with the same email address are always an option, albeit a pain in the rear to switch over if you need to do it frequently enough.
Paying real money though for a name change I don't quite like. Maybe feathers, but I wouldn't use wings for that. Wings are for when we have monthly exclusives (like a lot of other sites do to keep them up and running). We wouldn't abuse something like that- but I know you mean it with good intentions.
It was a good idea!
