@Kep
So, I'm about to kill your argument about SPSM being narratively Naruto's "Most Powerful" form any any significant way from his base.
Hagoromo gives Naruto and Sasuke each half of his Chakra:

Note: It's confirmed he gave half of his Chakra by Naruto,
here
Now, let's start by saying there is no basis for Base Naruto not equaling Base Sasuke. They both recieved SPC in their base states. Naruto is using SPC the same as Sasuke in a base state, the only difference is, Sasuke in addition to SPC, recieved Rinnegan and Naruto recieved SPSM, but neither ability contains SPC. Naruto is using SPC in conjunction with SPSM/Kurama Chakra/Biju Chakra. The Later two form together to create SPC, but to an unquantifiable degree outside of the SPC that Naruto recieved from hags. This is proven because of the Juubi Jinchiriki. Naruto's SPSM Chakra Mode, isn't "SPSM" actually. SPSM has noting to do with Naruto's outward appearce except for the eyes:

Naruto's Cloak is a Byproduct of using all Biju Chakra:
Now, before you start with more unfounded claims, let's see what's actually said about what SPSM actually is from the Databook:
SIx Paths Sage Mode (Naruto Databook):
"From the ancestor of shinobi, a divine state is gifted, touching the principles of all creation, commanding all things in nature
The qualities for obtaining this technique are strict studying and using a small gist in chakra kneading sensibility. An iron faith to face any hardship and the guts to never give up. Furthermore, the returning incarnation and fate's guidance ― this power is granted by the Sage of Six Paths only to someone who holds those. Those who activate the technique come to understand the flow of all life, gain a deep insight at the world's origins and are able to apply it on interacting allies without changing the way of things. This technique isn't something shinobi choose to experience. It is a technique that chooses shinobi." ^SPSM is only supernatural State of Mind and also according to the DB,it also grants Naruto:
It does not grant Naruto the ability use the SPC he was gifted by Hagoromo, this notion itself is proved False by Sasuke, whom himself doesn't have SPSM, yet:
![0695-005 0695-005](https://vignette.wikia.nocookie.net/vsbattles/images/1/1e/0695-005.jpg/revision/latest/scale-to-width-down/180?cb=20181031172007)
Time and Time again, Sasuke has demonstraighted 5-B AP without Susanoo and is stated to have SPC, which is necessary for his feats. Base Naruto scales to Sasuke, this isn't up for debate.
But let me explain further why Naruto's Chakra Mode
"Isn't significantly above his base" , nor significantly above Sasuke.
So, Naruto and Sasuke both recieved SPC from Hagomomo, each gaining half his chakra as stated. Prior to this, Naruto's max was
6-B with BM (Not Counting BSM for obvious reasons). Kurama's Chakra outside of BM has no bearing on Naruto's Chakra. Naruto without BM or KCM or SM, pre having Kyuubi extracted is 7-A, maybe At least 7-A. That Chakra he had was amplified by recieving Half of Hags Chakra, wheich amplified his base as well as Sasuke's.
Naruto's Power (Pre-Extraction):
Naruto's Power (Post-Resurrection):
- 5-B in Base with Six Paths Chakra
Now you are asking, why am I not listing BM or whatever, well, that's simple. Kurama was not amplified by Naruto's Six Paths Chakra. Kurama doesn't have Six Paths Chakra. The only time Kurama becomes amped by Naruto's Six Paths Chakra is in BM, why?
Kurama Mode (Naruto Databook):
![Tumblr ola19hxqBe1urljpmo1 1280 Tumblr ola19hxqBe1urljpmo1 1280](https://vignette.wikia.nocookie.net/vsbattles/images/2/21/Tumblr_ola19hxqBe1urljpmo1_1280.jpg/revision/latest/scale-to-width-down/400?cb=20181031174039)
Kurama mode simply put is Naruto combining His Chakra with Kurama's to use Kurama's Full power. When they are not in BM, they are not combined and thus, Kurama's Chakra is not amped.
So, when I say Naruto's Forms are not "Significantly" above his base, I mean:
- 5-B Chakra + 6-B Chakra = Insignificant Buff
Now, we also know (As proven above), a fusion of the Biju Chakra results in Six Paths Chakra. Naruto had 50% Kurama at the time and unquantifiable amounts of Biju 1-8 Chakra, so:
- 50% Kurama 6-B Chakra + Unquantifiable Biju Chakra = Unquantifiable Six Paths Chakra.
Which Means
this Naruto is Unquantifiably above Base Naruto and Rinnegan Sasuke with (50% Hags Chakra + Unquantifiable SPC from a fusion of the Biju Chakra, which only amounts to a fraction of a Juubi Jinchuriki's Power considering he only has a Fraction of Biju 1-8 chakras).
You'd understand this, if you actually did the research.
________________________________
So, in regards to Base Naruto killing Momoshiki, yes, it's possible. SPSM Naruto is only insignificantly stronger than base Naruto. Even less so now that he doesn't even use Biju 1-8 Chakra, only 100% Kurama. So In the Boruto Manga:
- SPSM Naruto = 50% Hags Chakra + 100% Kurama Chakra (War Arc BM x2)
- Base Naruto = 50% hagoromo Chakra.
AND it's a known fact that a characters Offensive Ninjutsu > Their Taijutsu. So, Base Naruto's Ninjutsu can very well be > SPSM Naruto's Taijutsu and Physical Stats, which is proven in the Momoshiki fight as Boruto's Naruto amped Rasengan killed him.
I'll address the other stuff later, but I have a Mid-Term to get to, so....brb in a few hours.
