I agree with prawncracker. As much as I like to see the gangs intersect, there's a delicate branding going on with Disney and the Muppets. They are trying to solidify Kermit, Piggy and the gang as their own troupe of characters instead of a Sesame Street sort of spin-off that many people today seem to believe them to be. I'm tired of bringing up the Muppet Show to people and hearing, "My favorite is Grover!" or "I don't watch kids’ shows." I am going to provide Crazy Harry with their names and addresses!
It is important for Sesame Street to primarily be about learning letters, numbers and shapes in good humor. It is important for Fraggle Rock to be social consciousness, peace and harmony through songs.
It is very important for the Muppet Show gang to transcend both and just be irreverent. Social commentary, music and acceptance are all there, but it comes second to the Muppet gang's humor and it always should. They're allowed to get away with more than the rest of Jim's creations. In that sense they really do work without a net and that is what makes for more of a challenge.
The Muppets just need to be the Muppets for a while. Then they can open up to more crossover opportunities and maybe even bring back the Muppet Babies down the line. That's just how I see it.
