It seems terribly awkward, even if the grammar works out. They will more likely not be female.

I agree with Mister Micawber. If you say "They will be.." that is positive, and you don't need "to" I would say "They will more likely not be female." For some reason most likely sounds better to me than more likely, but I can't prove that it is more correct, so I haven't changed it. I'm sure you will receive more academic answers than mine:) -Belles
