Who would you like to see in a Supergroup?

The Traveling Wilbury’s were mentioned on a recent John Lennon thread and it occured me that we have no supergroups now and i wondered who you would want see in a Supergroup?.
If the Traveling Wilbury’s were to reform i would like to see Don Henley and Eric Clapton as new additions,But my line up for a totally new Supergroup would be.
I would like to see,
Stevie Nicks, Tom Petty, Sting, Bruce Springsteen,Pete Townsend
or
Ray Davies,Mark Knopfler,Phil Collins(drums),Elton John,Roger Daltrey.
