>I would say having more meshes is better then shapekeys in this scenario.
That is only true if your toggles are using a different material and texture than your main avatar. If they are atlassed together and using the same material then shape keys are better for toggling things even if they are rendered at scale 0.0001. Not to mention the Mipmapping of the texture that essentially makes rendering the hidden scalded down thing take really quick
