Ah, OK. I was assuming it was more like a "normal" cable clutch like what is on my FZ1.There is no clutch arm on a dl650. it has an actuator on the left side and pushes what looks like the same clutch rod through the the case. if you have seen both dl1000 and dl650 models with the sprocket cover off they look surprising the same except for the clutch rod actuator. dl650 is cable operated and dl1000 is hyd, It looks like the hyd SC would bolt into the same holes that the cable operated actuator uses. If the sc will bolt in, it would be a bolt in conversion. I wouldn't mind slotting the holes if that would make the sc fit. You would have to see both models without the sprocket cover in place to see how identical the actuator mounting holes look. Never know for sure until some one tries it.
Sounds like it would be pretty easy to try out then - just need some donor pieces from a wreck.
