I'm also going to be building a new wampa head with horns, shoulders & arms to replace the original puppet. this way i can also replace the weird looking wampa shot as it lunges at luke in the cave. I'm starting work on that later in the week so as soon as that is finished i will post some photos.

Have you thought of getting in touch with someone who has built various Wampas in the past? Such as Tom Spina whom I know from The Replica Props Forum http://www.tomspinadesigns.com/Sculpture.html. Scroll down to the sixth row. I also remember he built a full size Wampa a while back.
