Worthy Task... But I think you need to prioritize. Think rack that can be used as tent poles and not tent poles used as rack. Even my old heavy steal rack on my Western Flyer was subject to breakage. I do think that a sturdy, proven rack that could brake down into tent poles could have a place.
I love little projects like this, they keep the mind ticking. Consider 3D printing your connection rods???
