One thing I find interesting about this thread is, there are lots of posts about SMB disappearing when LMB are present in the same BOW, but no posts on MMB being the outcome. Do MMB occur naturally, vary rarely naturally or only in the lab?
It's happened, but it's unlikely, simply because the two species prefer different spawning habitats. I have dreamed about a small body of water where both species are sexed and added and the habitat is such that both prefer it. Someday someone will do this and it'll be amazing.
