Good start, I have the hypothesis, if the mc learns the thunder chakra mode and masters it at a level higher than the third raikage, I imagine that in this entire process of mastering the technique, his body and cells will become terribly strong, could it be withstand a transplant of Hashirama's cells? It would be great if he could withstand it and acquire the mokuton or else he becomes stronger, increases his regeneration speed, physical power and amount of chakra, you could also make his vagabond parents have some relationship with the gold and silver brothers by relatives behind, and could awaken that lineage, allowing him to carry some weapon of these brothers, he could also negotiate with orochimaru to learn the wise way of the snakes, obtain some sample of the juice body to try to acquire the ability to absorb natural energy passively and would not go crazy if he mastered a sage mode. Furthermore, I could also pay him to capture a hyuga from the main branch to transplant the byakugan, since these do not cause the same problem as the sharingan, and since Orochimaru can easily sneak into the leaf (it is just a matter of convincing Orochimaru ), he could also consider learning Tsunade's strange strength, although it would be difficult for Tsunade to teach him, unless he captures Sakura and tortures her to learn the method as well as the forehead seal technique, it is too useful, or First he obtains the byakugan and then with those eyes they try to see the movement of the chakra of the strange force technique to copy it. In addition, they should also develop the technological side in Kumo. Didn't they manage to create a cannon capable of destroying the moon? It would be great if that was brought forward and they used it against the Juubi if it managed to revive or to destroy the moon. Technology has to be used and there is a lot of potential.
