Historically, Maria of Aragon married Manuel I of Portugal upon the death of her older sister and his first wife, Isabella (who just so happened to be Princess of Asturias and Girona)

So assuming that Isabella does not die from childbirth giving birth to Miguel, and thus, remains Manuel's wife, who does Maria of Aragon marry into? Are there any royal bachelors left for this Trastamara Princess?
