Simon CowellJust slap a smug smile, a black sweater and a little bronzer and Mick can hold court on X Factor (though maybe on second thought, he should play Steven Tyler on American Idol instead?)
Margaret ThatcherIron Lady reignited the public's interest in Margaret Thatcher and we think ol' Mick can give Meryl a run for her money.
Karl LagerfeldC'mon, you know this would be great.
Damian HirstHirst just showed his dot paintings at every single Gagosian Gallery in a massive show and now, more than ever, it seems artists are the new rock stars. We'd like to see Mick skewer the art world's over-the-top-ness and prove that "rock stars are the new rock stars" once and for all.
A Member of One DirectionThese young blokes could take a few pointers from Mick and, sadly, an impersonation of someone in One Direction will help the rocker appeal to young'uns who don't know who he is. (Sigh.)

Gordon Ramsay
SNL has been heavy on celebrity chef impersonations lately: Kristen Wiig as Paula Deen, Bobby Moynihan as Guy Fieri -- we'd like to see them face off in a cooking challenge against Mick Ramsay.
Prince PhilipYes, this is a Bill Hader character but surely he wouldn't mind stepping aside for a frickin' Rolling Stone? We'd like to see Mick's Prince Philip and Fred Armisen's Queen Elizabeth have some shenanigans during her Diamond Jubilee.
Bruce JennerThis suggestion is a bit of a dark horse as it would require Mick to adopt an American accent but how great would it be to have him wear an earring and a spray tan and join SNL's Kardashian family?
