Yeah, that will work.
I'd need a link to your other profile and which one you would like to keep.
Just make sure you finish all games on the account you do not want to keep, before you let me do the merge.
After the merge you'd need to do a fresh install. Then you can click 'My Wizard' and enter the save code of your account there.
Hey potato, I've merged your accounts. Your old one is set to merged and won't accept any new games anymore, so please only use the new one from now on.
