Yep, if this is really happening, I don't care what it's on, i'm just excited for a new show. As for the writer, I really hope they pick a Muppet writer to be the head. Not to mention, if they want this to be a success the performers need to have some say in how the characters are portrayed.
Also, less important wish list: I really hope they keep Miss Piggy's character development from the end of the last show.
I also really hope that Yolanda, Chip, and Gloria Estefan (penguin) continue as main or recurring characters.
There were a couple of YT videos that came out last year with Robin and Walter, and those were actually really fun and cute. I'd love for that to continue, although it might not work now that Peter Linz plays both of them. Also, I think Walter still technically being the new kid, it would be interesting if he and Scooter formed a close bond, with them both being kind of nerdy and relatively normal compared to the others. Scooter can kind of help Walter navigate the insanity going on around him.
I've said this before but, my favorite part of The Muppet Show was not the sketches, but the backstage plots. To me, seeing the characters really play off each other as themselves was always funny and often had the most clever humor in the show. Unfortunately, most of the backstage plots were pushed to the sidelines by the sketches and the guest stars, so as a result they often ended up feeling rushed and anti-climactic. So, if I were in charge of the new show, it would be more of the stuff going on back stage, and maybe like two sketches. I still think exploring the characters' personal lives could be interesting and give them layers, but make it less adult.
