/cgl/ - Cosplay & EGL

Hey /cgl/. I'm thinking of making a Space Marine outfit based on a pepakura template I found and using foam. The issue I'm running into is the cosplay would require me to walk on stilts. While that in itself isnt an issue, it would make the outfit disproportionate in the arms/hands.

The solution I'm thinking of is making an arm extension using a foam insert where my hand will be in the forearm with a gripping hand made from a modified pic related. Anyone have one that can verify if something like this would work?
