It has been done on a triple groove pulley, and it looks good. Unfortunately, the pictures were missing today: (User PER).

What he did was to machine a larger hole in the trigger wheel, and mount it on the inside of the pulley grooves. Just a little bit of material had to be removed from the pulley to mate with the trigger wheel, which is held in place with two small screws. It fits kinda like a ring gear on a flywheel.
