You know something, if they're gonna go with Heyman/Reigns swerve, I think they need to go the whole hog, and bring Ambrose into the fold.
Have Ambrose turn on Rollins earlier in the night, and cost him the IC title. Then, later on, you have Ambrose interject himself in the Brock/Roman match, and Brock deals with Ambrose, Heyman pepper sprays Brock, Roman spears Brock, becomes the Universal Champion. So, now Universal Champion Reigns, and potentially the next IC Champion, Dean Ambrose, aligned with Paul Heyman.
From there, you could either add The Revival into the fold, and have that cool "Heel Stable has all the gold" thing, where they're all stood on the stage with a belt over their head, or they could go Two Man Power Trip with it.
