Cd,
When you get the design sorted out. Let me know.
As it happens, I'm converting a '72 Karmann Ghia coup to electric, and my brother-in-law makes high-end custom fiberglass auto-parts for a living (wings, skirts, noses, etc). The car should be on the road this spring -- I'll consider aero upgrades thereafter.
