LOL, I think you ARE free to change your name--any person, any time, can change his/her name. In fact, you don't even have to go to court to do it, unless you need proof of the name change--it is a common-law right everywhere, so far as I know.
Not that you probably are inclined to do that, but it sure would be tempting not to be Mrs. Douchebag, wouldn't it?
