whoops. Meant to say flexural strength not stiffness.

Laying up in kevlar only will give you plenty of impact resistance but
I'm not sure you'll get enough stiffness. A very good explaination is at

I've often also wondered if what you described could work though.

For your offsets, why bother with that small of a change? You're talking
about 3/16" difference. But I can understand if you want to be precise.
Especially if you're looking to sell these later on. You could assemble
a small piece of skin with lamination you propose and simply measure it.
