Randy Orton (from SmackDown Live to Monday Night Raw)

Randy Orton has been a part of SmackDown Live since the 2016 Draft. However, he has become stale on that brand and should arguably move to Raw for a fresh start. He has accomplished everything that he could accomplish on SmackDown Live and should move on to Monday Night Raw. He can be a star and face off with superstars like Finn Balor and Seth Rollins.
Shinsuke Nakamura (from SmackDown Live to Monday Night Raw)

This duo of Shinsuke Nakamura and Rusev is already treading water and needs to be separated as soon as possible. The Superstar Shakeup is the best possible way to do so. Shinsuke Nakamura should make his Monday Night Raw debut by himself where he can have great matches against superstars like Braun Strowman, Seth Rollins, Finn Balor, and Roman Reigns.
