I much prefer the original to the sequel trilogy, but I certainly understand enjoying the sequels. Last Jedi in particular was a good film with several impressive performances and sharp, smart ideas that Rise absolutely neglected or destroyed, and Awakens was a fun time. Only Rise is thoroughly and completely irredeemable and, yes, drags the trilogy down a long way with it. The studio that made a fortune off the MCU began the third Star Wars trilogy without even a loose framework of the overarching plot and themes they wanted to develop, and that was the fundamental problem.
Honestly, Rise doesn't even need the stars other then Kylo - Finn, Poe, and Rey could all be replaced with generic Resistance guys and the ride would be just fine. And OT characters won't help Smugglers - only ripping it out and starting from scratch will do that.
Anyway, adding OT characters to Batuu is the last place stingy WDW should invest cash. If they want to build a new, OT-focused ride, great! But Magic Kingdom needs capacity, Animal Kingdom needs rides, and EPCOT needs... everything. We can all deal with watching Oscar Isaac mail in a performance from in front of a green screen in his garage for a while.
