Wellll...I mean there are still a LOT of things inside that park that are film-themed. Attractions, restaurants, the entrance...I just have a hard time believing that they will be re-theming everything inside the park.
I tend to believe that film elements will still be very present in whatever the park becomes going forward. So, I think the tower would still be relevant.
But, even if not, there is historical significance with that tower. It was one of the very first things built. It was the original icon of that park. I think there is enough historical significance and enough nostalgia in the piece that would relegate it to something more than a pile of scrap metal. Re-locate it to All Star movies. Re-locate it to WWOS. Heck, re-locate it anywhere. (and before anyone says, "Do you know how much that would cost?"...I can take a guess and trust me, Disney's got it.)
