Better get dedicated derailleur with a clamp. From my experience adding a clamp to a derailleur designed for a hanger moves the derailleur back a bit. This makes the derailleur to work shit. Someone correct me if Im wrong. I've tried it on Shimano 8 speed and Campa 11 speed drivetrain - with a KCMC and not shimano clamp though.
