If he succeed to unity the shinobi world and bringin peace when rikudo couldnt to it, then yes but he could never in his lifetime be stronger than rikudo
Naruto will bring peace to the ninja world, that's where the Sage failed. So yeah he will surpass him in that aspect. In terms of power however, well I don't know.
In power probably not. He'd have to have all the tail beast and juubi. Not fragments of them. As for bringing world peace. sure why not it's his manga after all
Madara and Obito attained his power only after sealing the Juubi inside them. Base Ridoku solo'd the Juubi, and then gained even more power after becoming its jinchuriki.
