In fact, if Will wins against Swerve this month, and Danielson beats Will at Wembley they could replicate the mania double belt yes moment...but idk if that really works against the hometown boy will, so I would not do this.
I would have Swerve retain at FD against Will because The Family or wtv you want. Then you have 2 options
1. Swerve loses to Danielson at All In
or
2. (imo better) Have Hangman return and take the title from Swerve after rejoining the Elite - do it on a special Dynamite if you have to. Only for him to lose to Danielson in August. That way you ensure the massive pop for Danielson finally winning the AEW title and taking the Wolrd Title away from The Elite. There is a lot of runway between Forbidden Door and All In so there is plenty of time for Hangman to challenge Swerve after the next PPV
