Mario with a lightsaber has (sort of) been done. Both Smash Bros. Melee and the original Smash Bros. had a lasersword item that anyone (including Mario) can put up at use.Mario with a lightsaber, or sonic with a mario cap
from IGN Guides:

Like the bat, the Beam Sword can help turn the tides of battle. Everyone calls this one the Light Saber for obvious reasons, but that makes Mr. Lucas mad, so quit it. If you use this laser weapon correctly, you can really whack your opponent high into the air. You can of course pull a Darth and throw this weapon, too.
