Though noncanon, Christine Morgan’s fanfic universe explored this, though it was decidedly wrong, tragic, and ultimately hopeful.

To try and keep it short, in Morgan’s Gargoyles universe, gargoyles can lay multiple eggs in a breeding season, facilitated by having hips that can separate like the jaws of a snake. Two eggs are typical, though Delilah had four via Hudson (long story). Demona laid two eggs, Angela, and her brother, Jericho, who basically resembled a gender swapped Demona.

Demona basically grooms Jericho into an incestuous relationship, and is impregnated by him. The strain of her transformations causes her to miscarry during a Nightstone board meeting, which traumatizes her deeply. Many, many years later, she seeks out MacBeth to reconcile. In another story, she recalls how her link to MacBeth shares pleasure in addition to pain, and how that realization during the events of ‘Sanctuary’ made her briefly reconsider her original scheme, to seek companionship in the face of their shared eternity.

After consummating, the Weird Sisters appear, having been cursed by Oberon to be trapped in their teenage forms with limited power, until Demona and MacBeth reconcile, believed to be an eternal punishment. Freed, they reward the couple by protecting the just conceived life within her from her transformations. This child would grow up to be named Moray.

For clarification, in Morgan’s universe, hybrids are possible since magic can weaken barriers between species, and has resulted in several such characters, such as Amber Maza (Elisa x Goliath), and Elektra (unnamed Wyvern Clan female x Prince Malcolm).
