One thought would be to change the action for our stun or interrupt, instead of just waving our hand, have us throw our lightsaber I suppose.

Sages are meant to primarily use the force and our lightsabers are our last line of defense, we do occassionally deflect blaster bolts coming our way.

If anything, I would like to see a greater variety of things we pull from the ground and fling at our advisaries.
