Then later, after said program was dissolved or whatever, the thinning of the bloodline could result in a couple of generations down the line, Kurotsuchi simply possessing Lava Style.

Okay, now I see the difference from my earlier theory. You're saying that other advanced nature bloodlines may not have been involved at all, and it was just a mutation of Lava release alone?
