4) Former NXT stalwarts The Undisputed Era reunite in AEW (Adam Cole, Kyle O'Reilly, Bobby Fish & Roderick Strong)
Adam Cole has been on a roll ever since arriving in AEW. The longest-reigning NXT Champion in history is currently undefeated in All Elite Wrestling. He was immediately reunited with Kenny Omega and The Young Bucks of The Elite.
However, the arrivals of Kyle O'Reilly and Bobby Fish has led to them reuniting with their Undisputed Era leader.
There is one piece of the puzzle missing right now - Roderick Strong. He is signed with WWE and is coming off the heels of a lengthy Cruiserweight Championship run on NXT 2.0.
He has been working dark matches on Raw and SmackDown lately, but many feel that his time in WWE may be limited. If Strong comes to AEW, the full Undisputed Era reunion could come to fruition.
3) Former WWE Superstars The Straight Edge Society (CM Punk, Doc Gallows & Serena Deeb)
CM Punk's return to professional wrestling for All Elite Wrestling has been a fun ride for fans.
He has crossed paths with many individuals from his past already, but there are a few that would give the fans one of the most underappreciated stables in WWE history.
The Straight Edge Society was one of CM Punk's best periods of his WWE run. His group with Doc Gallows and Serena Deeb made a mark in a short amount of time with memorable rivalries against Rey Mysterio and others.
Gallows has appeared for AEW, coming through the forbidden door as IMPACT Tag Team Champion with Karl Anderson of the Good Brothers. Despite the two companies no longer working together, he could still appear for a one-off.
Serena Deeb is currently a staple of the women's division, and realigning with her old faction would spotlight her even more.
