These two don’t seem to fit, but The Miz is actually in a great position to assist King Barrett. Miz is actually one of the best tag team wrestlers maybe ever. He’s won a WWE Tag Team Championship 6 times over his career with 4 different partners. Barrett could be the fifth.
The Miz is a natural heel, and aligned with the King of the Ring would give them a lot of bragging rights. Miz could be the King of the Screen with his gimmick. Given Barrett just returned from shooting a movie, the two could say they bonded on sets and are aligned to take over the tag team division.
