I'll use a bit of discretion in how best to answer this.
If one jumps into the wayback machine and rewinds the clock to when SWL rumors were flying around about Speeder Bike chases through Endor and visits inside of the Mos Eisely cantina, then visually your mind can paint a picture of something similar to a stroll through New Fantasyland. Oh, look... there's Belle's cottage... and hey, isn't that Prince Eric's Castle... how sweet... and just over there, it's the Dwarf's house. Neato.
That could've been SWL. Many ideas, crammed into one space.
The lessons learned down I-4 with the house that Potter built is you really should listen to the Dude and make sure the rug ties the room together. Guests love experiences that make them feel like they are immersed in a location. Instead of taking all the ideas and trying to make them fit like some sort of IP greatest hits playlist, make a concept album.
Is there a SWL 2.0 on the drawing boards? No, there is nothing that I'm aware of.
The way our trip to the galaxy far, far away is being created is using the Potter mindset. It is a 360 degree immersive (love that buzzword... it really expands the paradigm doesn't it?) world that will serve as the gateway to our adventures in the form of attractions, restaurants, and stores. Had the greatest hits approach been taken, the possibilities for the future would've been limited.
Using this method keeps the door open for more jumps to hyperspace to different locales in the future... if it's the will of the Force... and budget.
