The ability of IPs TCM, Bride, and The Thing having “original story expansions” is in the general mobility of the characters. Leatherface, as a human, could drive to tge local Wal-Mart and live it up, if he wanted to. The alien parasite could infect a plane. The give you a variety of settings, scares, and characters within a single house. Even the JP/JW franchise allows more flexibility now that the dinosaurs are on the mainland.
Jaws really doesn’t offer. If you do a house that’s predominantly underwater, you’re far better off just doing an original (a la Knott’s The Depths) because you can have more variety of characters. If you do it predominantly on a boat, it will suffer from a lot repetition.
The people who clamor for a Jaws house, I think, are a lot of the same people clamoring for a Jaws ride. They want a shark. But, Universal Parks still pays and negotiates with Universal Pictures to license stuff for haunts. Why would Universal spend money on to license such a limited experience when an original would be a far better house? There are IPs that may not be in house, but can give the same sort of scares with a much better overall experience.
