I mean nagato in the State that he was in after absorbing narutos chakra and becoming young again. Do you think he could doe the same think to Konaha as he did with Pain, i mean him alone with the Usage of the Rinnegan Techs.??
Nagato on his own is much stronger than Pein, and young Nagato was healthy, so more chakra, and he knew Shinra Tensei because he stopped the Kunai's from Hanzo's troops, so I'd say yes, he'd even do much more damage
