What does Reddit think of allowing users to Change or modify their username?

My name is manmalade. I don't like it :( would you guys be yay or nay If Reddit allowed users to have the option to change or modify their username for a small fee. It would generate some extra money for Reddit and then you wouldnt have to wait a certain time to post comments, captcha ect like when u create a new one. Sometimes u wanna keep your account but just change your name. My name Is Florida!! :( why Is my name florida!?
