Silly question about my gamer tag name.

I was young when I made my name "WickedWisp/Wispy" and want to change it bevause wicked sounds evil and it sits uncomfortable in the back of my head now because I dont want correlated with that, I am hesitant since its my username on everything and dont know if its worth the hassle.

Is it that big of a deal? Or maybe someone can help me find a replacement? Everyone calls me Wisp as a nickname anyways, and I wish I had something more positive for the first half.

It doesn't have to inheritly be religiously related but Im not opposed to it. Just one of these things that its really insignificant but bothers me alot, I am sorry if it seems stupid to bring up or ask...
