Any Muppets we have to date should be included in a new show. It should all center around Kermit as the 'head' of the muppet gang--because he is!
It should be a comedy show about their personal lives at the boarding house, going to the store shopping, doing interviews, while they're working on movies or tv shows, while they're doing things backstage as The Muppet Show is being put on at the theater.
Special Guest Stars would be there, but not as themselves. They might be the teller at the bank, or the gas station attendant--ranging from good to bad guy characters, even as cameo spots if needed.
The Muppet Performers would be there, too, in the background shots of people, or in walk-on talking roles.
Do what they did with TMM and go on location and shoot the show, too; don't stay confined in the studios.
************************
If they do something else, then I want it back at the Muppet Theater with Kermit as the host again. I would like to see the backstage area and on-stage performances.

Another idea? The Muppet Show with a Live Studio Audience.
