I think if they wanted to do this, they could have.

I think the Black Fairy's origin story should've happened around 800 years ago. This is what I would have done:

Merlin had the Holy Grail back then, and the Blue Fairy came to him and told him that its magic was the only thing that could stop the Black Fairy's great power, with which she was threatening to destroy all the realms (increasing consistency between what Fiona tried to do and what the Apprentice said about Merlin vs. the Darkness). So Merlin forged Excalibur and fought the Black Fairy with it, but she managed to break the sword in half. Since she used her magic to do so, Merlin was able to tether half the sword (which he turned into a dagger) to her Darkness, with the intention of controlling her with it. The Black Fairy, as a last resource, gave up the majority of her Darkness before the Dagger could control her, and placed it inside Merlin's loved one: Nimue. With Fiona weakened by the loss of so much of her power, Blue was finally able to banish her to the Dark Realm.

Nimue succumbed to the Darkness placed inside her by killing Vortigan, managed to get the Dagger from Merlin, and everything else unfolded just like we saw on the show.

Fiona wouldn't have been a mother by the time she became the Black Fairy, but the origin story could've happened anyway: the prophecy said she would once give birth to a Savior, but he would die at the hands of a great evil. She used the shears of destiny on herself to get rid of that prophecy. A couple hundred years later, she would have had Rumple with Malcolm under different circumstances.
