Choosing to place the land in the canon and timeline of the sequel trilogy, aside, this is easier to achieve with Potter due to the nature of the IP. Hogwarts, Hogsmeade, and Diagon are integral to Potter and 95% of the series takes place in them. They also already had well-known fictional stores and restaurants in the IP to develop. Star Wars does not have either of these. The closest thing is Tattooine but then you limit other elements.
Personally, while I think hard setting the land in the sequel trilogy hurts it a little, I still think this is an evolutionary (not revolutionary) step in theme park design to have a theme park experienec be canonical.
