If sasuke could use the whole sousano as preta path host then I would give it to him, not to mention that abilities that only nagato showed which sasuke probably has would help him alot with such durable person. Stuff like ningendo or soul dragon which can literary take the soul of the opponent by going through them(naruto has no intel on it) would probably work if sasuke manages to restrain BSM ava from moving. Don't know honestly, sasuke has multiple ways of killing naruto while the later can only blow shit up. If sasuke had curse mark I would instantly give it to him though.
OT: Don't know, I guess I'll give it to Naruto high diff , it could go to extreme. His BM durability was already outstanding, add his senjustu to it and it'll be a damn tank. Only way for sasuke to stand a chance is to try using his rinnegan techs in close range(by this I mean get close to naruto's acual body not the avatar) but even then, there's high possibility of getting manhandled by frog kata, I mean one punch from naruto is destructive enough to do
