Never thought about it but yeah, if Yamato wants to become Oden she needs to produce 2 children. Ace is dead though so it has to be someone else in canon. If I were living in Wano I'd offer myself up to impregnate her no problem.

Sanji missed a prime opportunity in offering himself up as a sperm donor. He could sweeten the deal with bringing up his superior Germa genes, and then breed Yamato like a sow.
