Naruto and Kurama are friends now. Remember Power isn't everything, you guys could go watch DBZ if your invested into that kind of idea.
Anyway, to counteract that would be sealing the Juubi and we might need some Uzumaki thats an expert in Fuuinjitsu. Naruto doesn't have much knowledge in that area to be quite frank.
Perhaps, seeing that Orochimaru, Hashirama and Minato are some what semi-alive they all excel in Fuuinjitsu. Hashirama could try to supress and keep the Juubi busy along with Tobi and Hiruzen, whilst Orochimaru and Minato can deal with the Fuuinjitsu. To get the Juubi out of place, they would need to use the technique "Creation of all things" by doing that all of the Bijuu's, Eight and Nine Tails chakra will be back to place and seperated or it has to be sealed in someone that has a great deal of Chakra (which is unlikely for that to happen).
