Ive proven that those chakra fragemnts are very small. So much so that Naruto nearly died twice while he still had them. Which establishes kurama as the largest biju chakra he had during the war. So when he taps into all 9 chakra at once, gradually producing juubi’ chakra, kurama is still the greatest component of that chakra. So there is no surprise that entering rsm would resembling kurama mode. Don’t mistake have juubi chakra for having the actual juubi inside him. Naruto did not have the actual juubi inside, he was simply able to recreate a fraction of its chakra. This is proven by the fact that he could still speak to individual biju throughout the fight with kaguya. So since he doesn’t actually have the juubi inside him, he doesn’t go through the same changes as obito or madara, his skin doesn’t resemble the pale whiteness of the ohtsutsuki(he does get somewhat lighter though). Still, that produced juubi chakra was his rikudo senjutsu. That’s what he was waiting for and that’s what let him enter rsm.

If he didn’t need that juubi’ chakra for rikudo senjutsu, then why wait? Why not use his half of hagoromo chakra to produce rikudo senjutsu and enter rsm right away? It’s simple, he can’t without the juubi chakra.

To be clear what I’m saying is this: Since Naruto woke up, he was already staring to produce juubi chakra. He kicks the TSO he’s making lava ransenshuriken and dodging limbo. All of this is granted by gradually increasing rikudo senjutsu thanks to the mixing of the 9 biju chakra. Once he makes enough juubi chakra, he enters rsm.

Which is further supported by the fact that he can compartmentize chakra and is skillful enough with half of kurama to his chakra with others. Which kurama can also use Naruto to share his chakra with anyone. Since those 8 fragments were less than half kurama, both Naruto and the biju themselves are capable of working together and producing juubi chakra.
