Add to that list finding the usable bearings (all- head top and bottom, axle), machining an axle, machining spacers, etc...
It would be a challenge just to make it work, but it would be unique. While I've personally not had good experiences with springers (they tend to bounce), I think they look slick. I think it would look way cool on a TBA. Bragging rights do have their merits.
Is it would be worth the expense? Only you can answer that. If it is what you want and you have the $$$ and resources to source/fabricate parts- fill your boots, bud. Send up pics when it's done!
