Question for CF Moderators and public

My IGN: "Sonatrix"

I want to buy a name changer to change my name to "sonatrix" ( the only thing changed is the "S" to a lower case one)

Dont ask why, i just prefer lwercase lol, and yes i know its a waste of money, but my uncle just gavee me 20$ so i can buy zp....

So would this be possible or will it say "nickname in use" ?

If it says that i will not buy the name changer... for now......
