Honestly I would take a look at the star wars saga edition and the way the force is used there. Really using the force is a skill check which is charisma based (id personally have a specific attribute for each type like dex for water, con for earth, str for fire, and wis for air), and you have so many force points to pump into a specific kind of skill or spell. But basic force stuff can be used without really spending any points. (Like moving small objects and stuff like that). I honestly think that would be the way to go. Of course I'd probably try and create a new class for it. Let me know if you want any more help, this sounds like an interesting project.
