The attack on the Usos was fine,it gets them in, over the next few weeks have them continue to attack both the Usos and then Reigns. Heading into Payback everyone is questioning AJ's motives for having his Bullet Club brethren in the WWE and having them softening Reigns up, of course AJ denies all involvement. At Payback have Gallows and Anderson come out and cost AJ the match by unleashing a savage beating on him. Reigns enters the ring looking to make the save but instead joins in the beating down of Styles. Raw starts with Reigns being confronted by the Usos demanding answers for Reigns actions in helping the guys who have been beating down the Usos for weeks. Reigns says that he got nothing from helping his so called family and he is only looking out for number one now. Later that night Gallows and Anderson interfere in a number one contenders match costing Styles again, after taking everyone out the Usos come down to get some more of Gallows and Anderson. Reigns comes out and spears both Usos, Anderson gets on the mic and says nothing can stop the Roman Empire as the show ends with Reigns Gallows and Anderson standing over the Usos and the contenders. During the Reigns/Styles feud a fourth member could be added , maybe some who was teaming with Styles against the Empire, possibly Ziggler Ambrose etc. If it stays a 3 man faction then during a Raw Gallows and Anderson could say that AJ was wrong for leaving them high and dry in Japan after they brought him in, Styles interrupts saying that they were not the ones who brought him to Japan only one man convinced him to join the BC and he is here to help even the odds (que Balor's music). After multiple attempts to even the odds ( teaming with the likes of Cena, Orton, and Ambrose) Reigns says he is tired of beating on Styles and Balor and challenges them to one last 3 on 3 inside the Elimination Chamber all they need to do is find someone who hasn't lost to the Empire. Styles and Balor agree , start to fight with the Empire and while they are losing the 3 on 2 Seth Rollins comes out and evens the odds. After the Chamber match Reigns and Rollins feud for the title while Styles/Balor feud with Anderson/Gallows.
This is more or less how I was thinking it should go as well.
I agree that attacking the Usos was a fine way to bring in Anderson & Gallows, albeit a rather uninspired one.
At Payback, you've got AJ Styles vs. Roman Reigns for the World Title. Styles is the clear fan favourite, while Reigns is starting to ride that heel line. So you have to run with it. Have Anderson & Gallows come in and cost Styles the Title, aligning with Reigns. Reigns, Anderson and Gallows form a new heel faction called
Bulletproof. Reigns used to be in a faction called the Shield, and he still wears a fucking bulletproof vest thing so the name works. It would be heat on multiple levels. Heat from general audiences because it's a heel faction beating up a smaller guy and doing heel things, and heat from the stupid internet marks because Reigns is basically hijacking the Bullet Club concept.
Since Andersn & Gallows took out the Usos on their debut you also have the angle where the Usos can approach Reigns and ask him like what the hell are you doing working with guys like this? And Reigns can say he's doing what needs to be done in order to remain a World Champion, something they know nothing about. This could give you a match on Raw with Styles & The Usos vs. Bulletproof. All hell breaks loose and you set-up a Cage Match between Reigns and Styles at Extreme Rules for the World Title, to prevent any outside interference (and to go along with the gimmick of the PPV). Reigns would of course retain the Title. Reigns is the clear heel and you want to build up Styles chasing it more before he eventually goes over. You need to make the fans really want it, something that seems to be more and more of a lost art.
From here I wouldn't bring in Finn Balor yet. Dean Ambrose will have just beaten Chris Jericho to blow off their feud, so it's time to involve him as well. He can team up with Jericho to go against Reigns, but of course the two of them would be outnumbered still by Bulletproof. Brining back Seth Rollins to even the score here would make sense. Rollins never lost the Title, and they wanted to do Rollins/Reigns before he was hurt. In a Rollins vs. Reigns match people would cheer Rollins and boo Reigns anyways, so might as well write the angle to reflect that. Bring Rollins back as a babyface, but have him as an uneasy ally of Styles and Ambrose against Reigns, Anderson & Gallows.
At this point you have lots of matches you can book, and it can keep you running months and months. You've got Reigns vs. Ambrose for the belt finally. A rematch between Styles and Reigns. Reigns vs. Rollins in the match we never got to see. Reigns defending his Title agaisnt all three babyfaces (Styles, Ambrose, Rollins) in a fatal-4-way. You could do a War Games styles Elimination Chamber with Styles, Rollins & Ambrose vs. Bulletproof. You could involve the Tag Titles in addition to the World Title. There are so many possibilities.
Eventually yes, you bring in Finn Balor. As this feud is ongoing you can hype Finn Balor as this mysterious figure looking on from the shadows, build him up with vignettes to really add some mystique to his character, and make it abiguous who's side he's on. The same way Sting was booked during that original NWO angle, you weren't sure who's side he was on. The announcers can put over his past affiliations with Anderson & Gallows in Japan. Eventually, Finn Balor reveals his alleigiance...Imagine a segment with the three babyfaces on one side of the ring and the three members of Bulletproof on the other, Finn Balor is standing in the middle. Balor turns and points his fingers like a gun, aimed directly at Bulletproof...
Money.
