I don't know what engine you're using now or how the game is set up on the back end but if that's the case then it almost sounds like it'd be easier to just start from scratch with a new game engine like Unity. You already have all the assets and scripts. Yeah, it's a big undertaking but if you consider opening up the code to some volunteers then it can be manageable. Heck, go teach a class on game design and have your students do all the work.

On the topic of money - if there is a minimum monthly budget that needs to be hit in order to keep the servers running properly then you should post that and ask for donations. I wouldn't mind chipping in if it meant I didn't get disconnected every 3 minutes of game time.
