No, Naruto cannot even regenerate Sauske's sharingan. This is because Naruto had the sun seal. The sun seal, when used with it's counter part the moon seal, granted the power to seal a massive beast such as Kaguya just with a touch. Being a gift from Hagaromo, it came from his abilities.
Naruto in the sage of six paths mode can heal others (stabilized Guy's life force, resuscitated Obito Uchiha after having the Ten Tails ripped out of his body and restored Kakashi's left eye) so he can restore Sasuke's eye, if not the rinnegan then at least the sharingan.....
No. The rinnegan is created through the Combination of ashura and indra's chakra. Anyways, Sasuke can't unlock another rinnegan. He already has hashirama's cells(which has ashura's chakra) within his body and nothing has happened.
After receiving half of Hagoromo Otsutsuki's chakra during the final battle against Kaguya, Sasuke awakened a Rinnegan in his left eye, which allows him to use all the Six Paths Techniques, plus one space-time manipulation power that is unique to Sasuke's Rinnegan,...
Naruto can no longer heal people, like what he did with Kakashi, as he lost his sun seal, that he got from Hagoromo.
Like Naruto lost his Kurama, Sasuke has lost his Rinnegan, and he will likely never regain it.
Sarada is a kid, so she wouldn't be a good candidate for any type of vision corrective surgery for another several years. Even then, her prescription would need to have been stable for some at least a year before a surgery attempt.
Without Kurama, Naruto lost a big part of what defined his strength, and what also made him who he really is.
Instead, he started relying on the powers of his Sharingan and threw caution to the wind in many cases. His battle against Killer B and his skirmish with the Kages examples of that. The loss of his arm has given him a weakness he's had to work around, letting him show off his strategic genius again.
Although Naruto usually uses the Six Paths' Sage Mode along with the Kurama Chakra Mode, there is no reason he cannot use it without Kurama's strength. In fact, Naruto can still use the basic Sage Mode, which is enough for him to take down a roster of enemies.
The Rinnegan is one of the most powerful dojutsus and has allowed Sasuke to perform some impressive sets of techniques that he can no longer perform. Without the Rinnegan, Sasuke would be much weaker when compared to his best form.
Because Tailed Beasts are life-forms made of pure chakra, they are eventually reborn after dying. They will always come back, but until that happens, they're factually dead. So, deliberately creating some new Tailed-beasts to get Kurama back does not seem like something Naruto would do.
Can Kurama be reborn? Although Boruto: Naruto Next Generations has already shown a Ten-Tails, it is unlikely that Kurama can be revived or extracted from it. Furthermore, the Baryon Mode essentially uses up Kurama's life-force, rendering it practically impossible for him to be revived in some way.
According to a theory elaborated by fans, Sasuke never actually lost his Rinnegan, he just needs a catalyst to re-awaken it. The need to save Naruto could be the perfect one, as the two share the deepest bond, forged by fighting against each other and on the same side.
Naruto isn't a Uchiha so he wouldn't have gotten the Rinnegan anyway. His body isn't naturally capable of generating that eye. As opposed to that of the Uchiha.
5 Sasuke Has The Mangekyo Sharingan In His Right Eye
While his left eye evolved into a Rinnegan later, his right eye remained the same and he still has access to its powers. With this eye, Sasuke can observe and see much more than a regular Sharingan, making him much stronger than before.
But if Sasuke was given a new arm replacing his left arm with Hashirama cells then he would be so powerful and would get a rinnegan for his right eye, able to beat anyone so hard that no one especially Shin couldn't beat him, however Naruto would with his Six Paths Sage Mode, but he wouldn't beat him at his normal form ...
Sasuke Uchiha is the strongest known Uchiha in the Naruto series. He mastered the Sharingan at quite a young age and, following Itachi's death, gained the Mangekyo Sharingan. After implanting his brother's eyes, Sasuke became the only second person after Madara to have the Eternal Mangekyo Sharingan.
In contrast, Naruto's arm was recreated using Hashirama's cells, but bandaged to avoid looking like the evil White Zetsu.
So, which new-tailed beast would Naruto become? Naruto has always been a powerful character, but his possibility of obtaining a new-tailed beast after Kurama's death could make him stronger. The increased power from the new-tailed beast could surpass even Baryon Mode, making Naruto a force to be reckoned with.
Naruto has been able to harness and collect the natural energy around him in order to enter Sage Mode even after Kurama's death. However, the sheer quantity that he was able to harness was far higher because of Kurama.
Now that he is without Kurama, Naruto has reason to further develop his Sage Modes, mastering an even higher level of Senjutsu than he originally thought possible. With Sage Mode granting him access to all five chakra natures, his ability to learn new types of jutsu is essentially infinite.
By releasing the Strength of a Hundred Seal, Sakura can use the Creation Rebirth, a forbidden technique known as the "pinnacle of medical ninjutsu". This ninjutsu puts her body in a state in which it regenerates and heals itself so that she does't need to stop to treat herself or even be fazed by injury.
With the help of her seal, Sakura can heal and regenerate any part of her body without using medical ninjutsu or stopping the battle.
The Uchiha heiress also first awakened her visual prowess when she went to meet Sasuke for the first time. The emotional excitement from that moment triggered her first tomoe sharingan. This was also when she changed her clothes to the outfit she is most known for.
