I don't think this is oringinal. But is still possible. Hehehe. What make you to make your name swift stone? Swift mean flying stars. And stone is a kind of rock. That not logic.
They could not, and should not do this because what about your friends? They would not know your name changed and may accidentally remove you and they could be a good friend and not know... I guess they could notify all friends your name change next time they log on, but when you logged on you'd have like 5-20 notifications which coulld get very annoying.
