what to do with the hairless heads...

I've got a BUNCH of doll heads that I must incorporate into my project - however it is important to me that their identity be dissolved. They have already been scalped and their eyes have been gouged (sounds so violent, I know) so I'm trying to figure out what to do with what's left of their faces. I tried melting them... and the following 2 images are what resulted...

And this is what they look like all chopped up. If I decide to take this route I'm going to need lots of helpers... it takes forever!
