Yeah, if I remember correctly Minnie was not a fan of Katya IOTL, so the same divide likely occurs. One question is if this butterflies away Alexander II's death, at least in its gruesomeness (as I assume assassination attempts will still abound). It was seeing his grandfather blown to bits that left OTL's Nicholas II with the idea that reform was pointless and bad, so could a son of NA and Minnie (even with a more liberal father) come to the same conclusion?Yes. The second family of Alexander II is going to drive a wedge between him and his children, no matter who survives.
Also for fun, I decided to create an alternate child list for NA and Minnie:
