Don't know if it'd count as a "cheapquel" given the fact that it was one of the few Disney sequels that made it onto the big screen, but Return to Neverland had Jane already behaving like a grown-up thanks to WWII when she gets taken to Neverland as opposed to Wendy's wanting to remain a child forever.
Jungle Book 2 would be another exception, as its not so much a plot reversal but a continuation of Mowgli's story from the first movie. Because seriously, did anybody think that Mowgli would have an easy time adapting to life in the man village once he got there? That he wouldn't miss his old life in the jungle and want to go back, especially right away?
