the theory is sound... centrifugal force will distribute the beads so that the balance is established (state of lowest possible energy). I think that the washing machine people have used this for years... a ring filled with liquid is used to balance the load on spin dry cycle in small direct drive machines. Works well.
My only reservation is potential crush-and-grind due to beads running around finding their respective positions before the wheel gets up to speed. Sliding past each other they MAY, in time, produce DUST which, can possibly, stuff up the tyre valve, ie make it leak. If you can be assured that this is not a problem, then I would be tempted.
