I think a Kingdom Hearts series would be awesome aswell!

But my favourite part of the original Kingdom Hearts was at the beginning when all the Villains were meeting to talk about how to stop Sora.
So, I think I'm just obsessed with the idea of seeing a Disney Villains Spinoff...mind you, I've never seen House of Mouse: Disney Villains, so maybe if I see that, my mind will change
I'd like to see something like Peter Pan and Captain Hook's Rivalry before Wendy arrived and the story took place.
Also, I'd like to see a spinoff with Ursula, of how all the 'Poor Unfortunate Souls' in her Garden of Mermaid-weeds came to be where they were. And how they were somehow associated to King Triton/The Castle, Ariel or her sisters.
