Mystique the Mother

Is it time to finally acknowledge "Mystique the Mother"? Especially since she's the Mom of important characters? She gave birth to Nightcrawler, who was already introduced in the series. She also had an affair with Sabretooth and they had a son together, which of course makes Wolverine an uncle. This could be a good way to re-introduce Sabretooth into the series and give Wolverine some emotional/personal conflict. And, Mystique adopted Rogue. Since Apocalypse takes place in the 1980's, this is when she was born, and a way to re-introduce the character.
