That would totally sink so many ships.

Seriously though, I think that would upset the balance, as has been said here. It would also give Hasbro the opportunity to potentially ruin things with some sort of My Little Pony: The Next Generation series. Note that I say: "potentially". For some franchises that sort of thing has worked well enough, but if not done carefully such spin-offs can totally wreck canon without even trying.

Furthermore, I don't imagine that pregnant ponies walking around is something they are ready or willing to deal with on the show. Example: Cadence and Shining get married, later announce that a baby is due, then we never see them again until a few episodes later the baby is already born. Another good example might be the Cake babies. We never saw a pregnancy there until one episode suddenly babies have been born. It could be argued that in Equestria reproduction is some sort of magical occurrence, sure. But if the Mane 6 reproduce I'd think that the event(s) would be far too significant to be so easily handled off-screen.
