This is the sort of hack I envisioned for my NOS Mavic/Simplex DT shift levers pertinent for 9-Spd before I accepted that they were going to be just way too dang far down there on a 64cm frame to worry about if or how well they worked. If the functional capstan diameter around which the cable wraps as the lever is rotated was increased.by some amount, the wonderful shifting feel could carry on into the 9-Speed world.
I thought about a tube of a particular wall thickness to put the cable through that had a widened end to stop in the lever's recess for the cable end bead. The hole drilled through the lever for the cable enlarged enough to accept both the thickness of the cable and added sleeve. The bead recess enlarged, if needed, to continue acting as the stop for both the cable and the sleeve. Flexibility would help insert through the lever passage, being more rigid and shaped would cause less cable tension to make it take shape as would be operated and cause less "noise" to the shifting function as tension is taken and given during shifts.
