Is it possible for Richeza of Poland or Elisabeth Richeza of Poland, the daughter of Przemysl II of Poland to be the Queen Regnant of Poland and marry Wenceslaus III of Bohemia who at that time is still a Prince, so he would be a King consort or Prince consort before he becomes the King of Bohemia, I read that the age difference between them is just like that between Bonne of Bohemia and John II of France, is such a marriage possible and is it possible for Richeza of Poland to be the Queen regnant of Poland just like Jadwiga did in OTL.
