I mean you did say "they could collaborate on a longterm development plan for Walt Disney World." along with "They might also want to express their gratitude for Florida and Floridians publicly for having been generous over nearly 60 years in allowing them to operate in their home state with little interference."
That reads a whole lot like Disney should be thankful to even exist in FL at all and that FL should have a larger say than they already do in the running of WDW. Certainly, it's asking for a larger involvement in WDW than in any other business in FL, otherwise nothing would need to change. Kind of like FL taking over WDW.
So, yeah, I think you are calling for "the nationalization of Walt Disney World", at least by the state of FL not the the federal government.
