I actually think there could be "easy" fixes to help bootstrap this sort of feel for the land. Implementing canopies like they have at the
Fremont Street Experience in Las Vegas could allow for more movement overhead, and a deeper immersion experience that is both impressive and scalable. Glance at the sky in tomorrowland and see the "skyline" of the places, with futuristic skyscrapers and ships zipping overhead. Has the popular concept of a futuristic spaceship changed? Just re-render the canopy video to have different styled ships. Need some synergy for that "Flight of the Navigator" reboot they just released in 2033? Insert him in.
It's "old" tech by now, but it seems like this sort of experience in T-land would still thrill and impress - not to mention do a lot as a band aid for a dying land while they figure out something else to replace Buzz, Stitch and Monsters with.
