He died before Sigismund II (who considered him as a possible heir).Why not just let a Hohenzollern prince - the son of the Elector of Brandenburg's second marriage to Jadwiga, eldest daughter of Sigismund I, succeed Sigismund II instead of a Vasa? Marry said Hohenzollern prince to Anna Wasa to keep the peace (after she converted to Protestantism a match with the elector of Brandenburg was proposed) and the Hohenzollerns are the new kings of Poland?

Vienna Congress, Kingdom of Poland is made of Prussian and Austrian Partitions and is in personal union with Prussia, making Poles about half of population.

I once made thread about this in Polish site. Such POD has great potential-Albert Frederick would be at the same time elective King of Poland and hereditary Duke of Prussia, something several elective kings dreamed about-it makes transition of PLC into hereditary Hohenzollern realm easy.What about Duke Albrecht Friedrich of Prussia? He was supposedly, as a descendant of Casmir IV, a serious candidate in the 1573 election but lost due to his Protestantism and the opposition of Jan Zamoyski. So either have him win the election in 1573 or not go crazy and potentially win in 1576 (the crazy thing would be necessary in either event). Could be an interesting scenario.
