This is basically impossible or not worthwhile, UNLESS the bone transform gameobjects aren't actually "moved" and the mesh is only moved visually.
But on top of that, you can have 10 dynamic bones right now and still be Good ranked. no one really cares about the ranks though, if someone is bothered by dynamic bone they can just limit it locally.
you should only concern yourself with being poor/very poor in terms of polys/materials/meshes, because that's the only way you can actually get your avatar auto-fallbacked.
