Running cable stops and pulley wheels can be a bit fiddly, but quite do-able. Last weekend I had my '73 SuperCourse equipped with a 5-speed rear hub out for a 30 miler.
Now, you're getting me inspired again. I love the idea of the S5 hub. I even have a nice NOS 1980s S5.2 hub hanging around. This looks like a fun ride. What are you using to operate the bell crank?
