It would be a stretch, but say, if John Cabot, in addition to his American voyages, voyaged to the Barents Sea (leading to it being called the Cabot Sea?

) and reached Archangelsk, Vologda and Moscow (or maybe at this point it's still Novgorod), opening up lucrative trade relations (wool for furs?) between Russia and England ITTL. Then, when Henry VIII has his problems with the Pope, instead of splitting off the Church in England from the Catholic Church and making it completely independent---Henry adopts Eastern Orthodoxy, which at least has a major following in parts of Europe and which offers the ruler a larger measure of control over the Church than Catholicism does. In that case, we can see something similar to the Ivangorod TL in which Elizabeth may become Empress of Russia upon Ivan the Terrible's death. Or another English princess or duchess married to Fyodor, thus preventing Russia's "Time of Troubles".
