Of course, but those lands were not designed to be a living, breathing Star Wars outpost. You can't have it both ways - if it is supposed to be like Adventureland, have BGM playing, have rides from different planets, time periods, etc.
WDI made the decision to have this land built specifically to be a living, breathing Star Wars world populated with the citizens of Batuu, which would include roaming aliens, Jedi, droids, bounty hunters, etc. That is the fundamental conceit of the land. It is also fundamental to something called a "Star Wars" land - unique characters that fill any Star Wars world is what makes them iconic, not the buildings, desert, swamp, snow, etc.
If you don't have that community of citizens for this particular brand and creation, you are left with an abandoned, beige, closed door movie set.
