I have spiral wrap currently on/around the front brake cable housing and shifter junction box and nowhere else. The spiral wrap is inherently flexible, and I need something absolutely rigid--straight as an arrow. A spoke is very small in diameter, yet rigid. Put a wire along it and do a clean electrical tape wrap job and there you have it. Spanning the down tube's length will be the trickiest bit.

Thank you! In this case of keeping things, it's Recycled Cycles. They are a constant help and source. Spoiled to be close enough to do business with them!

Thank you! I still like mechanical shifting, and will continue to use it just because it's cheap and works well and is easy to set up and maintain. I think if Shimano made a completely wireless system that looked as good as their current wired stuff, I'd be immensely interested. Thankfully, current-era Campy shifters look pretty sweet and many of their components still look good. The new 12-speed is sadly not as pretty. Seems like they're in a bit of a transition zone right now. As for me with this bike, I've watched videos on how to set up and tune the system, I just hope it works. Electricity is still a bit magic because you can't see what's going on, just the result. Well, unless you had an Oscilloscope or something.
