The location of Astro Orbitor is not only terrible. It also made a fun attraction Dumbo-like boring. The best thing about the Rocket Jets was that the platform was above the People Mover. The ride was faster and you got a nice view of everything below. I'm so glad they haven't ruined this attraction at MK by doing something similar.
When they eventually redo Tomorrowland (again), I have a great spot for Astro Orbitor to go. They can move it to the second level of the Space Mountain complex, on top of the Magic Eye Theater. There is more than enough room up there, and the ride would look really cool with SM in the background. Structurally, I'm pretty sure this would work. But they can also reinforce the theater, or get rid of it altogether to accomplish this. There's also plenty of room for a queue for both rides.
As far as Toontown becoming a Star Wars Land, I've stated my opinion before that this is not a good idea. Toontown closes early every night when there are fireworks. Spending all of that money for a land that won't be open all park hours is a pretty lame idea. Although, if they were to connect the existing Toontown space with Big Thunder Ranch, to create one big land, I could see an Endor-type forest area back over there. Still, it would make more sense to me if they gutted most of Tomorrowland for a Star Wars project.
