So, the challenge here is to have the Kingdom of Sweden and the Tsardom of Russia or Muscovy get into a personal union, with a PoD after 1500 and before 1900.
Seeming that Russia, for a time, had amicable relations with the Protestant duchy of Holstein-Gottorp, religion wouldn't be that big an issue, i think, so long as the Tsar-Kings are religiously tolerant.
One point of divergence i suggest would be a Russo-Swedish victory in the Battle of Klushino (1610), ensuring that Poland never occupies Moscow and possibly resulting in the Russian boyars selecting a Swedish candidate to the throne. The alliance later evolves into a PU.
Any further thoughts? What would be the effects of such a new empire (or at least alliance) forming?
