I bought a ProTec Twoface helmet. It weights 525 g. On the other hand Hero2 weights 225 g (with water proof housing).
I don't think all the work is worth for the bad results you can get.
First let me say, I don't want to sound too ruff or stern, on you.
Give 'ead a shake mate!
What are you going to 'make' a helmet for?
Go out and buy one!
You talkin' about protectin' the ol' brain box, the noggin', the day ol' jelly doughnut!
This piece of equipment is not something to be messing around with, in terms of safety.
What ever you make will be unproven. And the only way you will prove it, is if you walk away, or not.
I look ridiculous when I kite. I've got a big old orange life-jacket--It's the vest, not the really old head through the keyhole type!--(people laugh until they have a problem and need to tread water, control their board and fix lines or just sit there and wait for the wind to come up. I just relax floating.) and I wear a bicycle helmet!
Super light, cheap and does the trick!
I've taken some real crashes and was in shallow water and the impact really stunned me. I blew of the plastic on the bike helmet somehow somewhere, too.
I've even tried a hockey helmet and it works just fine, too.
I've seen guys with snowboard helmets and kayak helmets.
Do yourself a favour and just go buy one.

You can most likely google helmet safety tests and replicate them.
PS don't listen to the nay sayers telling you, you can't do it. What they really mean is they can't do it. They are then applying there own limitations to your situation.
