I don't really understand how that would improve your situation; I think it would make it worse. Allowing the head to shift would tend to make the cutter dig in at on an edge as it torques the head, giving you a worse surface finish.
Maybe if you gave us all some more details.
Material
DOC
Speed & feed
Type of cutter
Do you have a measurable change in DOC, or just poor surface finish?
