Very cool. I did something very similar with the Stronglight 93 on my PX-10. 45-42-30, with a 13-28 7sp freewheel. My first 'half-step + granny' setup, and I really like it. How does the Cyclone FD handle getting from the granny to the middle ring? The SLJ double FD on mine can do it, but it isn't always exactly smooth- I often end up over-shifting up onto the big ring then dropping it back down...
I've got a Holdsworth to build up with a Cyclone set and Campy crank, so it's very good to see a 45t 'inner' will work as the big ring (going to see if I can get away with 42/46 double and a 13-32 FW on it, but likely will end up triplizing eventually). Red Clover is great stuff, breathing new & useable life into old gear and saving aging knees at the same time!
