Further research suggests that I need to be starting at 9 speed DA parts to match a modern shifter's cable pull. And DA-4700 bar end shifters seem to be... well, rarer than I'm going to invest in this build.
According to https://www.sheldonbrown.com/dura-ace.html (all hail Sheldon), Shimano adopted the modern pull ratio in the 6 speed 600EX, but waited until the 7700 to put it on the Dura Ace groups because they didn't want to obsolete their early high-end customer's investments straight away, even though they had found out quite quickly that the cable pull could do with being a bunch longer.
Could be worse, DA-7700 is a good looking set, but not as cool as those 7400 rear derailleurs.
