Just thinking aloud here and from my experience with automobile 
engines.  Would a device similar to the harmonic balancer on an auto 
engine work?  As I remember, it is essentially a fairly massive iron 
ring with some kind of rubber sandwich between it and the hub.  I think 
the rubber absorbs some of the harmonics.
