How about replacing the Wampa with jarJar? Then when Luke has been captured and is hanging upside down, JarJar comes over "Mesa gonsta eats da Jedi num-num". Then Luke suddely uses the force to pull the lightsabre out of the snow and chops the top part of jarJars head off, which then spins in the air and lands with a 'hissssss' in the snow. Then Luke could free himself, spit on the rapidly cooling carcase and give a little laugh before toddling out into the snow.

When Yoda tells luke not to go into the cave because it is strong with the darkside and something evil is inside. When Luke enters the cave, instead of DarthVader, we see JarJar and Luke quickly shoots him between the eyes. "not so damn evil after all, was ya!" chuckles Luke. Then he turns his back and swaggers off while flipping the bird to JarJars still twitching and smoking carcase.

Have Lando with a chainsaw and use the same "suck spinning steel SH*T head!/I'm reborn again" scene from Bad Taste. Then in ROTJ when Lando is in the Falcon and is heading out to attack the deathstar in the final battle, Lando can slip on his JarJar suit, pat his trusty chainsaw and say "I'm comming to get you B*st*rds!".

I'd gladly give my gears or circuits to see any one of those :o)
