Six Paths Sage Mode is a heightened state of Sage Mode. If Naruto can't use Sage Mode on the moon, he also can't use Six Paths Sage Mode because of the absence of nature. He can't collect any natural energy and he also can't connect to other Tailed Beasts because they all are still on Earth.
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.
After losing Kurama, Naruto needs to train in the Sage Mode arts once again and by doing so, improve its usage. An improved Sage Mode could help him get much stronger and possibly even take on an Otsutsuki once again, despite not having the power of Kurama anymore.
Can Naruto use Wood Release Jutsu? Theoritically, yes. Naruto is yet to demonstrate that he is capable of using Wood Style Jutsu. His arm was repaired using Harshirama's cells after the last confrontation with Sasuke, so technically he might be able to use it.
Yes, Naruto still has the ability to fly and can still use Truth Seeking Orbs. If you are wondering why Naruto doesn't use his flying ability only during the Gaiden Arc, then here's the answer: this is where he must leave the village.
Naruto is far from weak without Kurama. He still has immense chakra reserves since he's an Uzumaki. He can also still use Six Paths Sage Mode, Toad Sage Mode, the Rasengan, Rasenshuriken, and might still have chakra from the other tailed beasts. What Techniques Can Naruto Still Use?
Known to be the strongest of all the shinobi, Naruto possesses mighty powers that let him fight even the Otsutsuki gods until recently. However, after his fight against Isshiki Otsutsuki, he is no longer as strong as he once was since he lost Kurama, his biggest source of power.
In chapter 700 of the manga, the final chapter which takes place years after the events of the series, an adult Hokage Naruto uses Flying Raijin to stop his son, Boruto, from vandalizing the Hokage monument.
Naruto is able to use the Rasenshuriken freely basically because he enters sage mode which allows him to throw the Rasenshuriken because of the nature energy and his own Charkra combined granting him the ability to throw it, in his base form he couldn't he had to attack Kakuzu up close like an regular rasengan, which ...
Chidori requires having lightning release/style which Naruto has access to. Next, shape transformation. The Chidori also requires shaping lightning into a surge which Naruto could do because he's mastered rasengan, which is said to be the pinnacle of shape transformation.
It is possible for Naruto to Awaken the Rinnegan. I have come to the conclusion in which Naruto Uzumaki is capable of awakening the Rinnegan through DNA infusion similar to that of Madara Uchiha's way of awakening his Rinnegan by infusing Senju DNA which he acquired through Hashirama Senju with his Uchiha DNA.
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.....
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. Even if he technically can with his Sage of Six Paths powers, or so the fandom seems to think.
The latest Boruto manga chapter reveals Naruto has upgraded an iconic power, which grants him godly abilities in an entirely new and useful way. On the pages of the manga following the adventures of the popular ninja's son, Boruto, Naruto has upgraded one of his iconic powers.
Who is stronger Naruto without Kurama or Sasuke without Rinnegan?
Naruto would be the winner. Naruto has an immense amount of chakra and reserves, and also sage mode, which is significantly stronger than Sasuke's seal (Heaven). Sasuke without eye powers is just a very powerful ninja.
Minato even possesses greater control over the technique, using it to earn the nickname The Yellow Flash. He is considered the fastest shinobi of all time and gained worldwide recognition for his abilities.
