Let me through some more into this mix...
If SLoP moves to the Globe Theater, I am afraid this attraction has made a major redesign and could possibly incorporate....dare I say it....screens. This plot is so much smaller than any other plot in the Lower Lot. Universal won't remove Parisian Courtyard because this would create a major problem with removing food venues, office space, and restrooms.
My thoughts are that SLoP could replace Walking Dead for its queue and the ride could incorporate all of the real estate of the Globe Theater. This "could" be the lost maze location... Plus, if JP is closed in September, they may not allow the queue to be used for a maze.
If Diagon Alley is coming to WotW in the backlot, then I believe that a 2nd gate will come into play. There is no way we would have a land sit out there in the middle of nowhere and cut off the tram for Supercharged. Remember we have Orlando management running Hollywood now so that Creative can have more control on the product. And everything points to Orlando's product and experience coming to Hollywood.
Nintendo will still go downstairs. If JP refurb begins in September 2018 and concludes by December 31, then Mummy could always close early 2019. I know the park does not want to lose a coaster, but Nintendo is a tough sell for Stages 22-25
