I would re-write this year's Royal Rumble.Big Show would have gone into the event as champion, and lose to Del Rio in the manner that he did. As Del Rio celebrates winning the title, Ziggler cashes in and wins the belt. He claims he is going to win the rumble, and unify the titles at Wrestlemania.
The divas title gets bumped onto the preshow, and some video packages get dropped so the US title can be defended.
Cesaro wins and again boasts that no American can beat him. He runs through some of his feats of strength, such as Netralizing Khali and Clay, and claims this makes him pound-for-pound the strongest man in the WWE.
Sandow and Rhodes would win the tag titles. Bryan would get shoved into Kane hit with Cross Rhodes and pinned. Kane and Bryan bicker after the loss over whose fault it is.
The rumble would go much the way it did, except Ryback and Cena would eliminate each other towards the end, and Orton would win, last eliminating Ziggler, after AJ causes some distraction.
Punk would beat the Rock after Lesnar interferes. Maybe even keep the lights out Shield attack and restarting the match.
Over the next few weeks, Ziggler drops AJ, blaming her for his rumble loss and losing his chance to show off in a way noone has since Jericho. Ryback and Cena starts a face/face fued to head to wrestlemania and Rock goes after Lesnar. Also, Mark Henry returns to begin a fued with Cesaro.
Punk claims to have beaten all the current stars, all the legends and he may as well take Wrestlemania off, when Undertaker returns to challenge him.
Smackdown Chamber - Ziggler, Orton, Sheamus, Bryan, Kane and Jericho - Ziggler retains, thanks to Langston slipping him a weapon. Kane and Bryan destroy each other.
Raw chamber - Punk, Rock, Lesnar, Cena, Ryback and Miz - Punk also retains. Again Ryback and Cena eliminate each other (some sort of double pin), and Lesnar works for Punk, destroying Rock and Miz, before he is eliminated and Punk finishes off Miz.
This would lead to Wrestlemania - Punk (c) v Undertaker
Ziggler (c) v Orton
Rock v Lesnar
Cena v Ryback
Kane v Bryan
Cesaro (c) v Henry
Barrett (c) v Bo Dallas
Rhodes Scholars (c) v Usos
And the Shield v Sheamus, Miz and Jericho, who would all be victims of Shield attacks in the weeks before Mania.I can't believe I need to put HTML tags in this to make paragraphs.
