I had just read the latest update for Darkened Family by Kj_Feyborn https://archiveofourown.org/works/15248763/chapters/35368485 . An thought no one has written a story where Palpatine got pregnant. Obi-wan still becomes a Jedi. Palpatine didn't give his baby to the Jedi, he realised Obi-wan is his son sometime after Naboo before Order 66.
