Apparently it was Kathleen Kennedy's idea to build Galaxy's Edge in the Sequel era. Business wise it wasn't a bad plan, since you'd imagine getting tons of new fans. And for what its worth, the place itself is pretty era-agnostic, you just need to change out the First Order Storm Troopers and maybe the satellite dish on the Falcon and boom! You can be in a different era. Heck, they started to parade Darth Vader there. The rides themselves are actually pretty popular, regardless of the popularity or not of the movie (Rise of the Resistance is an incredible piece of dark ride technology and I want to ride it one day!). Galaxy's Edge had a rough start but it's actually a success, probably the best thing to come out of the sequel trilogy really.
....the whole massive and spectacular Rise of the Resistance ride, not the mention all the first order stuff ... that wouldn't be easy to re-tool! But I look forward to a day when we can all go to themeparks again without worrying about, you know, dying.
