Or how about have the villains do a teen/adult Halloween event at the studios. Have the Sith take over Galaxies Edge (can now use Emperor due to Episode 9.). Have Sids toys roaming TSL, do the Hades standup on the stage in front of the theatre, dress the bellhops up as ghouls, and for the big show have a Fantasmic where the villains win. Make it obvious in the marketing that this was a PG-13 event, not HHN, but not MNSSHP and have disclaimers about this not being for young children.
It would be a huge hit.
