Or
Disney Infinity Adventure
It would bring large large crowds!! Kids would go crazy over this!!!
With large sections of the park still geared to Hollywood, Disney Infinity Adventure wouldn't make a great deal of sense.
Questions like:
"Why is there the Chinese Theater in Disney Infinity?"
Would get asked. The answer would be tricky. "Well back in the late 80s they built this park as a working studio with a theme park connected to it, but that didn't work out so eventually we changed the name and built some new lands.
The theater... That's from back then."
Sticking with the established and flexible theme of Hollywood gives them a lot of place to play with and of course preserve key elements. Now it does seem like any of the behind the scenes stuff they pursued will be gone. Completely. Instead it will be about living in the movies (or riding the movies from Uni's playbook). Sets, scenery, and props will all be gone. That's a loss. Hollywood Studios was pretty unique in that respect, and the last bastion over at Universal Hollywood is also being completely reworked into a theme park.
The idea of a behind the scenes movie park was so cool, but is dying a slow painful death.
Now as to Disney Infinity. Could they build a Disney Infinity Land? Yeah. Could they even do a small complex? That would be cool. Would it work as the theme for DHS or DHA? Nope.
Infinity is mainstream, but not super mainstream.
