The more I think about it, the more I think it might be "fun" to map out an entire Tommy Westphall-style diagram of inter-ride references and continuity cruft. With "fun" in quotes because it would be both a lot of work and maybe not very satisfying. I mean...if you take every theme park Easter egg as canon, the Haunted Mansion also shares continuity with Star Tours and therefore the entire Star Wars universe.
I would REALLY like to see someone do this! It would be terrible work to do, but boy would it be helpful for people trying to parse out the increasingly-connected lore that keeps going into the parks. Also, IIRC the Star Wars and Indiana Jones universes were (perhaps jokingly) implied to be in the same continuity already (R2D2 and C3PO appeared as hieroglyphs in both an Indy movie and in Indy’s Great Movie Ride sequence), meaning that Star Wars is connected to the Disney Parks Hell Universe at TWO points!
