while i do like the idea of opening up that land, i don't think what as put there is the best idea. first i think bringing radiator springs racers over is fine and really fleshes out the whole Pixar Studios area better with a true e ticket attraction, however bringing over the entire carsland would be a huge mistake. you would be taking thunder away from DCA, its redundant and unoriginal, and just plain rediculous considering you have a pixar land directly beside the new proposed land about a pixar movie (just hating disney's idea and rumors not your concept in particular). as for star wars land, i agree that a major expansion of DHS has to include this but it needs to be connected physically to star tours somehow, it cant be in two separate parts. if you demoed the backlot express QS, this would be a pretty easy task. in place of some of the extra space you have left over in that huge expansion pad i would also/instead expand the muppets into a full land, demo the current backlot tour allowing RSR to move slightly forward and expand Pixar place by bringing over laugh floor and building the door coaster and a new, better pizza planet or ratatouille restaurant, and then make a sort of backlot land in the furthest back part of the expansion pad with a new, much improved backlot tour just to name a few things.
