At this point they need to just close everything at DHS except for ToT, RnR, and Fantasmic and MAYBE Toy Story. Create a temporary backdoor entrance near Fantasmic and allow entrance as part of an Epcot ticket (or PH obviously) and go to town on construction, full steam ahead and open up a brand new revamped park in less than 3 years Star Wars Land and all. In the mean time, you can eliminate tiers at Epcot and DHS as Frozen, TT, Soarin, TOT, RNC and Fantasmic/TSMM would create enough offerings to spread things around evenly. Obviously I know this would never ever happen, but I thought it was an interesting idea.
