For the universe's sake, ignoring merchandising, I would say that it's possible in very rare cases. However, in a matriarchal society a stallion would have to show a vast amount of initiative, character strength, and adhere to a disproportionately high standard of composure. Males in the show have been shown as either average at many things, not good at anything, strongly specialized at one skill while lacking the ability to do anything else proficiently, and/or shallow. The stallion would have to be so awesome that he'd be annoyingly non-relatable and a douche because, given what we've seen, a stallion wouldn't have gotten another shot after any "Lesson Zero" comparable behavior.
