what you're doing is really worthwhile
That's a great frame.
That triple crank looks beautiful and having properly low gears is such a nice thing
getting the fd right is going to be trial and error and might take a while. What are you planning to use? Consider pic rel, the crank/fd are inseries, should be perfect right? But they actually don't work together. The fd should match the curvature of the big chainring, but on this frame the back of the cage ends up way back off the chainring. That means a lot of trimming, which is annoying with friction shifters, and with your microshift brifters would be straight up non-functional. Getting a pull ratio for indexing that works together will also be a bit random for you.
