One of Henson's major problems, and I've said this millions of times by now, is that they need someone to partner up with for even the smaller projects. They haven't had a good partner since they parted ways with Columbia after Buddy and MFS... actually, even later than that since they distributed all the movies and the TV show up until the Disney buyout. Hit was terrible, Weinstine was terrible... no one else wants to step up because they didn't make Avatar.
A smaller indie firm COULD make Happy Time Murders happen. That would be a nice springboard for someone to partner up for Fraggle Rock (Regency isn't going to be enough) or, dare I say Dark Crystal 2.
