I am writing in my current timeline that the Bourbons inherit England and were stripped of their French titles, can the Bourbons inherit the Russian throne via and the new Royal House is called Bourbon-Romanov..
I know a Bourbon was elected King of Poland at least once, so if something like that coincided with the Russian Time of Troubles, you could see the Bourbon or a descendant of his claim the throne of Russia. OTL, the Poles occupied Moscow in 1618, so something like this isn't too far out. Maybe a marriage to shore up his local powerbase leads to a Romanov match.
To get this far, the new branch of the Bourbons would certainly be Orthodox, and would bear little resemblance to their cousins in France.
IIRC that would coincide quite well timewise. I think the chap in question rushed home from Poland to take up the French crown on the death of his brother...Ah, but that would make him a Valois I am thinking of....
There must have been a Conde who was in the running for the Polish crown a decade or two later... but I don't think got it?
Heck, memory!

A possibility is the Bourbons really going Protestant - if they don't inherit France then there's no "Paris is worth a Mass" and since Orthodox rulers felt closer to the Protestants...
Did the Orthodox feel closer to Protestants? Do you have any links so I could read about it?
I'm going from marriage policies - the Romanovs married Protestant German families, and I remember Ivan IV propositioning Elizabeth of England...
