Just a thought.., They have that styrafoam or some kind of insulation material in a can that you shake and shoot out of a can.
Perhaps you can use wax paper around the hulls and make a form out of the stuff.
Who knows, it may work.

I used that type of foam in 5 ltr rectangular plastic water containers about 7 years ago. It made them very solid. I ran a loop of shockcord through a hole in the end, with a stopper knot inside the container (before I squirted in the foam). The shockcord went round the hull and was held around the neck of the container. The guy who bough my Hawk is still using them.
