What could've happened is that Kaguya maybe transformed him or something to become Zetsu and her will, that may also be the true reason of why Zetsu calls her mother -- Kishimoto always makes plottwists.

Your theory is getting bashed because its impossible.

Your logic:
 * 1) Hagoromo and Hamura worked together to seal their mother and the Ten-Tails (manga fact).
 * 2) Hamura, who worked the seal his mother away, then becomes Black Zetsu, who spends the next couple of centuries trying to revive her.

Logic.

Kishi's logic:
 * 1) Hagoromo and Hamura worked together to seal their mother and the Ten-Tails (manga fact).
 * 2) Before they could do so, Kaguya created a manifestation of her will, which became Black Zetsu. (manga fact)
 * 3) Black Zetsu then went on to manipulate events in order to bring about Kaguya's rebirth. (manga fact)
