This is actually exactly the next step he needed for his career - this cocky heel works for him
I would like to see him wrestle a bunch of the old/older guys. An obnoxious and cocky 21 year old Gen Z guy pissing off elder millennials and grizzled veteran Gen X wrestlers is a relatable story that pretty much writes itself. They had that dynamic with the Jericho feud but there's more that can be done because they had to keep it relatively short because of Jericho fatigue.
Give him a squad of some other Gen Z wrestlers too and let them terrorize AEW. with the most annoying Gen Z antics. This could be a good way to rehab Hook and make him actually interesting for once. The Swirl could slide in there as the tag team. Then there's Jordan Oliver and Alec Price down in ROH who Wayne has a ton of history with. Top Flight could be an option too if they get motivated.
Most of the rest of the men's roster in that applicable age range are either higher on the card than Wayne or tied up in their own faction and doesn't make sense to have them leave at the moment, like Garcia and Yuta, for example
Would be a good spot to bring Billie Sarks up from ROH, but a ton of that women's roster is in that Gen Z age range so here are plenty of options to work with there.
