Anybody been there done that?
If so, which model?
Or is this just a marriage that will
never be?
i dont see one that looks to do what you are trying. besides, by the time you buy a shimano RD and a shiftmate you will be at the cost of a campy RD

not really. here is my best attempt to explain. the indexed lever pulls a prescribed amount of cable and then the RD transfers that cable pull into lateral movement across the cassette. different able anchoring locations and pivot points on rear derailleurs will effect how far the RD moves per millimeter of cable pull.
