Garth is out, because the character depicted is not (as far as we know) a shapeshifter.
Why do we expect that the character will be a carbon copy of a previous character including the story? Apart from the distinct possibility that the character is brand new, it could be an old character with a new story and a new persona. There some hints here and there that the character is not an evil villain, but a complicated person, who is in some way dear to the crew or the federation. You could use that to discount Khan as well. Of course, that could all be false.
No superpowers? No Gary Mitchell. Not a distinct bad guy? No Khan. Not a shapeshifter? No Garth. Not a spoilt teenager? No Charlie. No ridiculous outfit? No Mudd. Hey, wait, it's Korby.
