It's very possible, however it's not all up to Disney. The Muppet Family Christmas has other Muppets that are not owned by Disney. Fraggle Rock is still own my The Jim Henson Company and the Sesame Street Muppets are still own my the Sesame Workshop. So this isn't just in the hands of Disney themselves.
Plus it's not all Disney's fault that the some episodes of The Muppet Show has been cut. Copyright laws, what are you going to do
. And I think the same would happen here agian. As many of us know, The Muppet Family Christmas has come out on VHS and DVD already, however a lot was cut.
So like I said, it is possible. You know the saying never say never. Sadly, however, it does look all too good.
