Let me uncover one little but obvious secret: there's no reason for Ao to be the user of Rotation. The technique's key part is not a Byakugan, but the ability to release chakra from all the tenketsu of the body. Only Hyuga members possess bodies with such an ability, while Ao himself isn't a Hyuga. So the Byakugan possession doesn't actually give him what it takes to use Rotation.
