Notice the OP said "re-re-name" instead of "re-name". The answer is no, you cannot rename your username if you already renamed it in the past. One possibility you can do is to create a new account and create a different username. For the wikis you've contributed (if not, the wikis you often contirbuted), it's advised to mention that your new account (and state your new account name) will be in use, instead.
