I must be getting lazy. I'm thinking inside the box too much.

The solution should have come to me before -- it is so obvious.

When Mark Starr mentioned that someone had a feathered GP which did not look twisted, I followed that line of thinking and assumed that someone simply started with a tree instead of a 2x4. Thanks for the hint, Mark.

If you start with a tree, or maybe just with a 4x4 instead of a 2x4 you could lay out the blades at any angle you wanted and achieve your feathered paddle without needing to do any steaming. Power tools will help with removing all the extra wood.
