Could it be done? Of course!
Will it happen? Probably not.
The process of making something like this is long, and never ending. You have to go through many legal things and so much more to make a project like this possible. Not to mention basically re-creating the game on your servers, and keeping it alive and running smoothly. As the game grows, the team behind it has to be twice as big, or really on top of things.
Another challenge, being non-profit. They can not accept money from people who wish to donate or make an optional monthly payment, if they do they will be considered as to making profit off the game, and that could result in a law suit, as the game is still Disney's intellectual property. So the money must come from the people behind the game, and only be put into the game.
