I like the idea and you should be able to get similar results from a few (3 or 4) web cams and a morph program. Then it's already digitized and you can mess with it as much as you'd like.
I saw some stuff that a film student did in his dorm room like this and it was very good. He used the web-cams and one of the morph programs that are available on the net. Not sure on his OS, coulda been Linux.
