It don't give him access to his past lives but it do give him life force needed to wield WR for sure. I said that Naruto should be able to use WR via SPSM, not by being Hashi's successor, 'cuz SPSM grant user the innate ability to grasp the nature of chakra and comprehend all universal things, not that hard to understand. And i said should, didn't made it a fact ...

Also, via SPSM he can use much more jutsus with different elements but he don't, same goes for WR. It does not fit his fighting style he got used to and we didn't see much of him as Hokage to show us if that changed, he mostly used taijutsu ...
