This thread fails in its very premise, the incarnates themselves aren't literal reincarnated souls of long deceased individuals, so since Naruto isn't Ashura as an example, even if Neji had been an incarnate, he wasn't Hamura in person.

But could Neji have had Hamura's chakra? Sure, since it's possible with Ashura and Indra, I don't see why it shouldn't be with Hamura or Hamura's sons. In fact, upon observing Naruto and Sasuke at first, Kaguya thought them to be incarnates of Hagoromo and Hamura, indicating it's possible and that it's not something unique to just Ashura and Indra.

EDIT: but to actually answer if I think it to be true, then I do, Neji indeed was special and might have been an incarnate, we may never know though.
