1) Evolution will reform after Triple H betrays Shawn and ends the DX era, they reform to take on Randy and remove the belt from him. Orton is then forced to get Legacy together to help him, but he finds out they are badly injured from a mysterious backstage attack. He has no other choice but to find new partners. So he fights against Evolution by himself for a few shows and then suddenly Jericho and Edge appear to help, together they form a new stable named, Saving Grace. They then dominate the WWE one by one and put an end to evolution and become the new top dogs of the federation, ofcourse holding many belts.
2)Next, since I am indeed a mark for him, I'd build Mike Knox into a feud with Orton. This is caused by Orton thinking he is unstoppable and holding an open challenge to anyone to take him on. And no, NOT ANOTHER CENA FEUD lol but a fresher one, where Knox accepts and gets in some mic work showing he actually has decent promo skills. He will tell Orton that he has been in the shadows too long, and that now is the time he shows people what he can do. He then makes a new catchphrase on the spot to Orton; "When I dig your grave, you'll thank me in hell." Which he will later use regularly in his other promos. Orton will later realize he is outmatched, and he will complain to management that he is treated unfairly and he doesn't deserve facing a monster like Knox, but they tell him it was his fault for issuing the challenge, and so he trucks on alone with the monster until one show, before knox comes out, he beats him so bad and then punts him(if possible in the game) and tells him to; "Enjoy the match....." which leads to their final bout in which Knox still wins and ends their feud on a light note.
3)In this rather intriguing storyline, Jericho begins picking on the rookie Zack Ryder, slapping him around, insulting him backstage, taking stabs at him whenever he has the chance. Ofcourse Ryder gets sick of this so they feud, but everytime Zack ends up losing over and over. So Morrison steps in and offers to help and train him to better himself as a superstar, Jericho does not like this at all and ends up brutally assaulting Morrison when he least expects this, forcing Ryder to continue the feud alone and with zero help. One show later Morrison gets his revenge by running down during a no DQ match between Chris and Ryder, and helps Zack beat the crap out of Y2J and wins the match for him.
4)My final idea, and probably the most simplest, DX takes on E and C for an epic feud. E and C will cut funny and comedic promos making fun of DX, while DX fights back with comedy of their own, until E and C get tired of it, and end up playing dirty attacking and surprising DX in any way they can making them the lesser of the feud. But they still manage sadistic humor insulting them and taunting them as they destroy DX once and for all. To counter this, DX goes to Vince and asks that he allow DX take them on in a string of gimmick matches. Hell In A Cell, Ladder Match, Table Match, Steel Cage, and even a First Blood and TLC match. This makes both team literally go through hell leaving the last match with one winner to end the feud, which E and C will cheat at by having one of them have a weapon hidden in their clothes or something and knock one of the DX members senseless, and finishing off the other one winning with dirty tactics.
Thoughts?
