Dibiase should get rich gimmick, like his father, but also have two ladies in classy dresses accompany him to ring every time.
I wouldn't mind seeing a new superhero gimmick, not Hurricane(even though he was awesome), but a new guy.
Tyson Kidd should get a pure submission gimmick, mostly win with Sharpshooter, I would have him start by beating guys like Kofi, or Cesaro.
Gabriel should stay the same, he actually has some charisma, but I can't remember them giving him any promo time since a little bit during the Nexus.
Morrison should come back, and form team with Miz, or if Morrison doesn't come back, Miz go back to 2010-2011 gimmick.
Kofi will stay where he is for rest of career, he won't go down much, but he won't go up either. If a heel turn happens, he'll rise to a possible world title reign, and then fall back down to midcard life.
Drew McIntyre can be revived to everyone's amazement, he is damaged, but can possibly recover. It would have to be a slow 2-3 year process, of having him leaving 3MB, and winning match by match, by beating people like Slater, and Santino, and then moving up to Kofi, and Cody Rhodes, and then moving up to Cesaro and Barrett, and then to Randy Orton, and Sheamus. He can slowly move up rankings, and then reach destiny of chosen one, and become champion of the world.
