#4 Big E should win the Royal Rumble and challenge Roman Reigns if he loses the WWE Title
Despite Big E and Roman Reigns being on separate brands, WWE can pit the two against each other at WrestleMania 38. However, for this to happen, the New Day member would have to lose the WWE Championship and win the Royal Rumble Match.
Big E is set to face Reigns at Survivor Series, which can lead to further animosity between the pair. He would want to avenge his potential defeat while reuniting with The New Day in the process.
Charlotte Flair to return and wrestle a CURRENT CHAMPION?
If Big E moves to SmackDown, the company can pull the trigger on a full-blown program between The New Day and The Bloodline without any interruptions. This is another great option if Reigns is to lose the Universal Championship at WrestleMania 38.
#3 Seth Rollins can return to SmackDown for a WrestleMania 38 feud with Roman Reigns
Speaking of RAW stars moving back to SmackDown, Seth Rollins is a very intriguing opponent for Roman Reigns. The two have a lot of history together and have teased a title match for a while, despite both being heels. Their eventual confrontation will be epic.
With the Red brand stacked with top stars, that confrontation may come sooner rather than later. Rollins may win the Royal Rumble Match and challenge The Tribal Chief, moving back to SmackDown.
The Architect can play the anti-hero against Reigns, who is the ultimate super-villain. Few main events would deliver better in the ring than Seth Rollins and Roman Reigns finally going at it.
