Psionic Space Ninjas, I like it and I too intend to try them in my games. I think though, wouldnt telekinesis be more appropriate instead of levitate? I don't exactly recall any jedi ever floating around in the movies or the Clone Wars animated show.
The levitate power also works like telekinesis. Also, if you wanna snipe it, don't hesitate to change it up and make it however you like. Here are the design notes:
B/X Elf advancement, with Carcosa-style psionic powers instead of spells. LBB fighter HD and fighting capability LBB Cleric Saves, but advance in groups of 3 instead of 4, due to the high XP requirements of the class. Light armor and AC bonus to fit the "dexterous fighter" theme of the class
Have fun with it! I tried looking at some modern star wars rpg books for ideas for the force powers, but everything was "+1 this, +1 that" and I found them very lame. Geoffrey's psionics system saved the day!
I read levitate as the technique that allows them to make huge leaps. That's how I'd play it, anyway.
Given Carcosa's unique dicing system, I'm also inclined to tweak "increasing damage" ability (which is awesome) to +1D at first, and later +2D; i.e., if your damage die for a given fight is a d6, it would increase to a d8 or a d10, depending on your level.
And of course the quest for the parts to make a lightsaber is pure Carosan goodness...

Levitate would probably be like the gliding leap Vader makes off the freezing chamber steps (if I am remembering the movie correctly.) It seems like a lot of their powers were just enhanced versions of things a person could do anyway. Might as well call it Levitate in D&D terms.
