Where would you Rank Orochimaru in the Akatsuki

[Floydical]

Can't Samehada just slowly consume Amaterasu before it kills Kisame? He doesn't like fire but he should be able to absorb enough to keep Kisame alive. Isn't Susanoo made of chakra and Giant Shark bullet simply eats it and GG? How does Kisame not beat Itachi in this scenario?
