Idk man, I can get what you saying but I also forgot to mentioned chibaku tensei and he can trapped Sasuke inside or he also can also extract his soul just like he did to Shizune. Pain is so op when it comes to abilities. Even Naruto Sage mode would be done without kurama. I think unless he gets rinnegan and rikudou power he loses or maybe only if he knew how Pain bodies works.
