There has been talk about moving the Astro Orbitor back to the Observatron platform and so on. But this idea doesn't have to worry about having AO ot having AO. The idea lies across the Pacific in Hong Kong.
The Tomorrowland in Hong Kong Disneyland has a really interesting entrance, with a large planet (a la Mission:Space) with Tomorrowland on metal work surrounding the planet
* Different views of the entrance *
I think that would look really cool if they found a place to put that in the front. With a fountain and a rotating planet. It would make the entrance more interesting and those useless rocks could be removed. Or encorporate them into this new idea. The planet could even change colors at night.
