King's has the "Top Hat" I have not tried it.
"King's Sales & Service Group (A.K.A. King's Sales & Service) is proud to announce the arrival of its revolutionary new Top Hat Sprocket Adapter. The Top Hat Sprocket Adapter precision mounts the rear sprocket onto any ISO standard 6 bolt disc brake hub AND helps to put the sprocket in the proper location to help ensure a perfect chain line! (The adapter can be used WITH OR WITHOUT a disc brake system or disc rotor if you just want to take advantage of its superior mounting method). "
