I am thinking Team Heyman VS Team Booker T/AJ. With Heyman's team winning causing Booker T and AJ to be replaced.
Now you're thinking, that's a good idea. Have Heyman and his goons try to simply take the company over and Booker T/AJ joining forces to stop him. Leads to Survivor Series with Heyman taking control of WWE with his guys vs. WWE's guys.
CM Punk (WWE Champion); Brock Lesnar; Wade Barrett ("open for business," Heyman obliges); Dean Ambrose (could be a mystery team member); Cody Rhodes (could run a "tradition vs. revolution" angle for Cody with him beating up his own dad when Dusty thinks Team Heyman's gone too far, blah, blah, blah, and it would be nice for Cody)
Team WWE/Cena/AJ/Booker T/Good Guys:
John Cena; Triple H (enlisted in the war by Cena's pathos the week after Hell in a Cell or something); World Heavyweight Champion Sheamus; Rey Mysterio; The Miz (caps off his babyface turn by reluctantly but heroically joining the good guys)
Something like that.
