Have you ever thought of taking a crack at making one of these in 1/6 scale? I saw this a awhile back and thought now that the new predators are coming out that this would go great with their armor as a custom.

Oh man! I've seen pics of that Bone-Hunter predator mask / bio / helmet and it does look very cool.
Sadly, I don't have the sculpting skills to make a 1/6 scale version of that work of art. I have trouble making two putty balls the same size.
That would be great if someone would tackle that project. I would purchase one (or more) for my 1/6 scale mask collection. It could be made to fit on the Hot Toys Berserker predator or a modified Falconer.
