I’d need 3 things (no matter how crude)

the Star Destroyer fighting with Tantive 4, as seen via Luke’s binoculars (which could be used for enhancing the “Luke cleans the moisture vaporator” scene from E4)
Luke in his landspeeder flying from the top right corner to the bottom left corner (which could be used for putting into the deleted scene where he almost runs over the old lady on Tatooine)
a small CG wampa jumping from snow and being blasted by the probe droid (we have the scene in animatic)

Anybody here knows how to do these 3 shots? Or did somebody already create these 3 shots?
