Try it? I don't have my barons (same overall construction as Dukes) anymore, but I believe the heel piece is the same, just slides off the track. If it fits on the griffon track then it will probably work. It would be the same as putting a jester heel on a griffon track, the construction is all the same (assuming they are the same generation).
