Here goes nothing...
Step one - Zayn and Owens, not surprisingly cost Team SD at SS. Kurt Angle keeps his job. Feud between Owens/Zayn and Shane gets more heat.
Step two - continue feud with Shane and Owens. Add a member to Owens squad. Preferably someone with Indy and NXT credibility but really it doesn't matter. Just adding another member makes it feel like something bigger is going on.
Step three - in the build to the Rumble let it be revealed that there is some higher power behind all of this. Not a god, but just a person who brought Owens/Zayn/#3 together out of hatred for Shane and Vince and what WWE is. Shane demands to know who it is. Owens says that if they want to know they need to give that man the #30 spot in the Royal Rumble. Next week Shane comes back to agree to the deal.
Step four - nearing the end of the Rumble, leave three groups/generations of wrestlers in the ring. One group being Owens/Zayn/#3, The Shield, and then Cena/Orton/Jericho (can't think of anyone else right now that works better).
Music hits for #30, "If ya smell!" Crowd goes apeshit but nothing happens, "Gong!" Same thing but nothing happens. "Sexy boy" crickets. "Glass breaks" but nothing. Total silence while everyone watches, then it hits " Time to play the game!" HHH leaves Gorilla but in a suit and tie with a confused look on his face shaking his head no, the wrestlers are all shocked and confused. Clearly HHH was behind all the violence against Vince and Shane and this is his way of using his NXT connections to get the main event of WM and take over WWE. But he is denying what everyone knows and his confusion is a farce until his music stops and we hear a massive guitar rift leading to Cult of Personality and the return of Punk.
Punk puts a shocked HHH to sleep and joins the Rumble to win it. This was all his plan to get what he wanted all along, a main event at WM where he faces AJ (see the irony there) for the title.
I know, I know, wishful thinking. But it should happen. It would certainly make WM more special and the build more entertaining. It could also get mainstream press as the story behind it goes beyond the regular scripted storytelling and booking.
I don't know, its a reach and know whatever WWE does will be a disappointment to me but I enjoyed sharing this fantasy booking and I hoped you enjoyed reading it. Blame Kapu for starting this thread if my post ruined the next six months of WWE programming for you.
