i think its possible since he is child of prophecy whos supposed to be stupid strong
no naruto wouldn't but sasuke.....yeah he would crush so6p easy
Actually naruto is much more closer, since he actually tamed the so called most demonic spirit in Naruto verse " Kurama ". Madara had to use EMS to tame kurama, and even then he couldn't achieve what Naruto has. The full co-operation of kurama, which is what the sage tried to embody into his sons. Yes Madara has rinnegan, but he doesn't have the bond with the bijuu's like Naruto, which will eventually become the juubi and possibly the next in line for the title of "sage".madara is closer than the sage than naruto, infinite chakra

Naruto dont need Rinnegan.
If Naruto manage to Control all the Natures energy then he can beat SO6P.
Natures energy is far more than juubi chakra.
If only Naruto manage to do that.
Imagine kurama learning sage or at least co-operating in absorbing the sage chakara. The ratio's at which kurama absorbs sage chakara is much MUCH higher then any human could.
Kyuubi + Extensive Senju chakaa - Plot Hax = Sage of Infinite Paths.
