Never ignored that. The chakra was one, meaning he already had the chakra required to evolve his Sharingan into a Rinnegan per Kabuto's hypothesis.

Kabuto calls it a "natural evolution", therefore your theory is contrary to fact.

The manga specifically states his chakra got split between them. His Rinnegan went no where.
