If it reduces vibration without causing more friction, perhaps. But another variable we have to contend with is rotating mass. Rotating mass can help fuel efficiency in only certain rare cases, like when going uno and down a series of small hills. But in most other areas it hurts efficiency.

I think once vibration is near zero then there becomes a point of diminishing returns.
