If they have no intention of putting Miz back in the main event, turn him face and put him back together with Alex Riley. But have them be booked as equals rather than boss & lackey. Maybe they could be a jokester comedy duo similar to DX. They don't need to be a permanent tag team, just have them watching each other's backs and protecting each other from 2-on-1 beatdowns.
I'd also like to see Zack Ryder reunited with Curt Hawkins. Hawkins could turn face, since he hasn't worked as one since they were the generic Major Brothers in ECW. Hawkins could cut his hair and be a Broski just like Ryder, but he'd be more mellow, toned down and too cool to care. Ryder would be a huge idiotic goofball while Hawkins would be the straight man to his partner's antics.
