Naruto+kurama+bee+hachibi+kakashi+gai> tobi+incomplete juubi. Naruto+kurama is already > 2,3,5,6,7 and bee+hachibi > 1 + small kurama chakra+ his own tail coupled w/ gai and kakashi
the power will be the same but not the amount of power, he still will have power but not full power, why wanted tobi to summon the juubi full power, either way he won't have full power because kyubi isn't full power either, it will be incomplete no matter what
