One of my very first alternate timeline ideas after joining this site was a timeline where Mary of Burgundy survived, and this is a much updated version of the Habsburg lineage for that TL.

[1] The Yorks remain on the English throne due to Elizabeth of York's betrothal to Charles VIII of France remaining in place after 1482.
[2] I couldn't resist giving Burgundy to Margaret and marrying her to Philibert ITTL. Also, Charles I of Savoy dies childless in 1486 so Philip II succeeds to Savoy much earlier than IOTL.
[3] Elisabeth and Louis are children of Vladislaus II and his ATL wife Elisabeth of the Palatinate.
[4] Maria enters a convent at a young age, as part of a promise that her father made to his dying mother.
[5] Catherine of Aragon is born male ITTL.
[6] Daughter of a surviving Ferdinand II, King of Naples and Maria of Aragon and Castile. She is the only child of her parents, as her father dies just a few months after her birth.
[7] Afonso, Prince of Portugal survives ITTL to become Afonso VI of Portugal and João is his eldest surviving son by Isabel of Aragon and Castile.
[8] Isabella of Austria-Burgundy was engaged to Vladislaus II at the time of her death so Max had to come up with a replacement real quick (he tried Anna at first but she was only 12 and thus way too young for Vladislaus).
[9] I'm not sure who this Hedwig Jagiellonica would marry...suggestions are welcome!
