No, it's not, sorry. You have to make a new account with that username.
Nope, not possible. You'd have to create another account if you want a username change.

I don't think you can change your You tube username iv'e tried and tried and just cant seem to find out how to change it. :o
No, you must make a new account.
impossible. make a new account
saddly you cannot do that. you would have to create a whole new account. P.S. if you have to start a quick list of all your fav. songs and videos on your new account. ( use artists name and click on the + sigh in the corner ) then save

GOOD LUCK
