My idea is this...
Taker vs. Lashley
Taker vs. Batista
Taker vs. Cena
Taker d. Lashley by DQ after ECW-ference
Taker d. Batista by pinfall - wins WHC
Taker d. Cena by DQ when Batista turns heel, interfering and spearing Taker.
That makes Taker 17-0 at WM, changes the hands of the title that needs changed, and sends the fans home happy after Taker/Cena destroy Batista.
On the undercard...
HBK vs. Edge vs. Orton - Contendership for Raw Title
Kennedy (tweener) vs. King Booker - Contendership for SD Title
