Tomorrowland can very easily be changed in to Star Wars Land, it all practically writes itself. I would be somewhat against the idea but how hard would it be to give Space Mountain a SW makeover (which I believe they are actually doing temporarily), change out the cars and scenery in Autopia to pod racers, Star Tours is already there, retheme Nemo to that underwater city in SW, Switch out the rockets for Star Speeders on the Astro Orbitor, create new facades for the attractions... I could go on and then squeeze in a whole new ride. That way you get the best of both, the Tomorrowland classics with a new updated and more cohesive theme without the two lands exisiting awkwardly together. That way that expansion area can be used for another expansion.
