Its obvious whats going to happen.
The fox was able to give kakashi chakra, so logically he should be able to take it from other people.
He also said he'd explain it to naruto later.
So, with that said, the army's going to share their energy with naruto, and so will bee and the other tailed beasts since naruto knows their names.
I still see no other way for this to end aside from naruto becoming the reincarnated sage of the six paths.
