At this point AEW and New Japan should just do like soccer teams and loan out guys they aren't using and/or getting stale to each other. Plus I think Juice isn't without any upside, he was perfectly acceptable as a mid to upper card tag team guy before the attempt to make him into Generic Bullet Club Heel #532 for some unknown reason.
Also while watching Sunday Night Football, they showed an ad for the Premier League (NBC has the TV rights here in MURICA). Made me think that would be a great opportunity for someone who owned a team in each league that maybe has another business they run that could benefit from being advertised on NFL and EPL games.
