I agree, disney acquiring ghibli would be great content for d+, and I could see one of the major characters being kinda like an unofficial princess and given a cool land in the Japanese disneyland. They are already building a ghibli themed park in Japan but it doesn't have rides, it's a peaceful walk-through experience. Keep it that way imo but give DL something big and unique and fantastic, replace toontown/IASW area and go nuts or maybe build on the expansion area like where they built GE in disneyland California but with a ghibli theme.
In another universe, disney already owned ghibli and instead of a fantasy springs expansion at disneysea, its a ghibli springs expansion
