Everything but the Falcon? What exactly do you mean by this? The characters/the Falcon itself or the Ride system? Because if you aren't talking the ride system, the ride will be based on The First Order, which has not been done in a Disney park other than the little "march" that they currently do at DHS.
I think it's ridiculous we're having this discussion about the drawing power of Star Wars. If someone went around saying the same thing about Potter or Mario, they would get Universally (no pun intended) blasted for that hot take.
Star Wars is one of the biggest IPs in the world, next to Potter, Nintendo, Marvel and Lord of the Rings. Just because it's had a presence doesn't mean people won't show up. Although if people don't show up, then I say great! I'll actually be able to get on the rides.
