My roommate completely changed her name, when she converted from Islam to Catholicism. Her family disowned her and kicked her out so she didn't want anything to do with her father's name, so she changed her last name to her mother's maiden name as it wasn't as obviously arabic, and picked and English first name she liked.

I think you have well thought out reasons for wanting to change your name. Go for it, if you think it will make you happy.
