I'd Love to see it if Legacy can get the win.
DX is a massive force in wrestling and i agree that it will be fun if they go back to old DX stuff. But its no good them just destroying them. I wouldn't mind throwing Orton into the Mix and making it a 3 on 3 match with DX getting a younger member (although that will never happen).
They are planning on making SS massive so i think big matches are required almost a mid year WM Card:
Cena vs Orton
Jeff Hardy vs CM Punk vs Rey Mysterio (has to be some varity there and they are all good workers)
DX vs Legacy
Big Show / Jericho vs Brothers of Destruction
Its a start of a promising card to me. I think you'll find SS will actually be a stronger card than Mania this year in an attempt to boost its prestige.
