There's Little Mermaid (already mentioned by YourMother), though that's the only really big one left at the moment. There's also Pocahontas, Hercules, and Hunchback which I can see doing pretty good ($200-250M DOM), but not huge.
Give it about 10-15 years and we might see Lilo & Stitch come back. Heck we might even see Pixar films being remade by then. Another 10 years we'll probably see remakes of all the Disney Revival films. I'd imagine a Big Hero 6 remake would probably just be part of the MCU if that's still around.
