I'm not sure entirely what your idea is, but in order to connect parks or lands, you have to have a compelling story idea that has a darn good reason to do so. In this case, I'm sorry to say there isn't one. The company looks at the parks as separate entities (business units). Epcot's reason for being, so to speak, is entirely different than Studios. Plus the logistics have to make sense as well, and in this case they don't. There's already a transportation system in place that guests utilize to get from park to park. There's no compelling reason to do a specialized connector above and beyond what's already in place. Universal had specific reasons to do what they did, and it has ended up increasing the attendance in their parks, as well as driving 2 park ticket sales, even for guests only taking one day of their vacation.
Although an interesting idea, it's not in the cards.
