I have found out that some Disney live-action science fiction comedies share a setting in the form of Medfield College:
Medfield College is a fictitious university used as the setting for several films (namely science fiction comedies) made by The Walt Disney Company. Medfield College is named after the town of Medfield, Massachusetts. According to town historians, friends of Walt Disney lived there, and he would...

That means that the movies are all a shared universe, I guess (I would check them at some point just in case).

Also, maybe the 1997 remake of the Absent-Minded professor (titled
Flubber) is the same universe, given that the character has a different first name? I need to check.
There is also the fact that a character named like the titular absent minded professor is the only other inventor in the first
Honey, I Shrunk the Kids movie that encourages the main character with his invention, so I would need to check if it is just a reference or could be the same character.
The Medfield College is mentioned in different incarnations of the
Journey Into Imagination ride on Disney World, but including theme parks would led down to an enormous rabbit hole (as we saw when Pro Bot shared that the Mary Oceaneer thing at the parks implies that Indiana Jones, Atlantis: The Lost Empire, the animated The Little Mermaid and Pirates of the Caribean are the same universe, somehow), but lets dig a little bit:
-The host from the second and third version of the Journey Into Imagination also gives a inventor of the year award to the
Honey I Shrunk the Kids guy in the
Honey, I Shrunk the Audience attraction, which links back to the Honey I Shrunk the kids movie again.
-The characters Figment and Dreamfinder from Journey Into the Imagination receive an origin story in the Marvel series
Disney Kingdoms: Figment #1-5 and
Disney Kingdoms: Figment 2 - Legacy of Imagination #1-5, but since the Imagination Institute from the ride seems to have been replaced with the Academy Scientifica-Lucida it may be a reboot set in a a different universe (although the Medfield College is again referenced). Also, all of the Marvel Disney Kingdoms comics were supposed to be set in a shared universe based on Disney World rides, so I don't know if it also leads to the previously mentioned Society of Adventurers and Explorers Universe from before, again, supposing the rides and the comics are not different universes.
-In 1988 Disney released a series of educational shorts starring Figment titled Language Arts Through Imagination, since it has guest appearances from Alice (from Alice in Wonderland), Peter Pan (and Wendy), Merlin, Owl and Gopher (from Winnie the Pooh) and the Reluctant Dragon (from the 1941 short of the same name) all of them could be potentially the same universe. Then again, since Figment and the Dreamfinder seem to be able to travel through time and dimensions, maybe these are a different universe(s).
