hanging the whole name is also not cute. You should always keep that piece you are known by. Ain't nobody here for that Miley / Hannah tea.
Changing a name to something completely different will only confuse people and make them question who you are.
Ex: Rem --> Gatsby
Gatsby wasn't a bad name, but it made people go "Wait, who even is this?" until they realized that the person was a mess and ATRL addict so obviously it had to be me.
Thought Wendy's was classier than this. 
Glad we understand each other.
