Won't happen, but the show could do with a ground up reboot.
Blasphemy I know.
Hell take a year off.
Cut the show down to an hour.
Retool the opening monologue.
Get rid of all of the current segments.
Redo the set to give it a fresh look.
Up the pay to make it a destination vs a spring board to better things.
Get rid of Lorne Michaels and Don King and bring in fresh younger blood.
You can't get rid of Lorn Michaels, he has a major ownership stake in the show now since he came back in the mid-80's.
