You forget that even Yata Mirror only defends from element attacks, not purely physical attacks, or presumably attacks from a PS. In addition, Sasuke could teleport Itachi outside of his Susanoo using his swap places hax Rinnegan eye. Itachi is a no contest fighter in this fight. At current levels, only Kaguya can compete with the two of them. It is POSSIBLE that Sasuke alone could not defeat Itachi, but I am 99% positive that Naruto could solo everybody without challenge. Sasuke could likely solo everybody without challenge, but may face minor difficulty against Yata Mirror. Only if it holds up against PS, and he can avoid Sasuke long enough after being teleported outside of his susanoo.
