after he gets PS fused with yata and tatsuka i think he would become unstoppable, all attacks would be reflected and once someone is stabbed he would be sucked into the sword... the basic durability is generally really high and with intelligent use of his genjutsu he would take down everyone except madara, kaguya, so6p and maybe juubidara...

but this is only a IF... with his limited chakra pool he would have a hard time getting susanoo to that point ^_^
