No hostility here man lol.. And if this ever happens trust me, I'll remember this.. however currently I'm just going off facts
I understand it's a theory that I made, but read my latest one.
In hindsight, here's my hypothesis: The God of the Narutoverse is the Juubi. It is completely illogical that a normal human would be born with the eyes of the Narutoverse. Not even remotely possible. It is said, when Rikudou sealed the Juubi within himself, he transcended humanism to become a God. AFTER he sealed the Juubi. The eyes of the God is the Rinnegan. We know that the Juubi's eye superimposed is the Rinnegan. We also know that the Bijuu have a lingering effect on their Jinchuriki's; Gaara's manipulation of Sand, Naruto's whiskers, Roushi's Lava Release etc. Each one had an effect on them. Now, why wouldn't the original being itself have the largest effect of them all? Answer that. Now, we also know that Naruto gained the chakra of 6 Bijuu. It may or not have been a retcon for the 1-tail, as the Juubi saw Shukaku inside Naruto as well. So basically the premise is: If a person were to gain the essence of the Juubi itself (The Bijuu's comprise the Juubi's chakra and are chakra itself) then that same chakra would culminate within the said person and have the same effect as the original Juubi did on the Sage; The awakening of the Rinnegan.
That's for Naruto.
Sasuke is pretty simple. We have barely seen his EMS techs. He didn't go past the Skeletal stage in his battle against Kabuto with Itachi and we know that Madara gained PS, AFTER he gained the EMS. So it is logical to assume that Sasuke would gain PS. Enton armor is also predictable because Sasuke is a master of Enton and in due time can probably develop in on a similar level that Hashirama did with all his Mokuton techs.
The most debatable ones here are the Spiritual objects. We know Sasuke said "I can feel yous Power Nii-san". This was referring to his eyes when he transplanted Itachi's. There is nothing we can say or not say to refute the possibility of him having Totsuka+Yata as Itachi's power was transferred to him through the transplantation.
Just to put it out there: PS+Enton coat+Totsuka+Yata is relatively equal to Full BM Naruto+Rinnegan. The Rinnegan isn't severely damaging the PS because CT would get smashed by the PS Susanoo blade aided by the Enton destruction.
It would be a relatively equal battle and would show that with these new powers Sasuke and Naruto were to have surpassed Madara and Hashirama.
