Pesronally, I feel this is more Duginist esque, "normal" Eurasianist(Gumilov-esque) or some sort of hypothetical ethnosupramacist Rodzaevsky esque path than Savinkov. I think Savinkov won't be as insane, especially since they have made it clear they will dial back the more blatantly Nazi elements of his regime. He will take all of Central Asia, the Baltics, Ukraine and White Ruthenia, and perhaps the islands from Japan but it's perhaps more likely he would puppet Finland under some Russian administration along with Poland under some collaborator. That said, I can see some batshit Cordreanu-esque or Pelley-esque nutcase radical thats worse than Savinkov(maybe takes over in situation where Savinkov dies but his party still maintains powet)go for much grander goals, and I could maybe see the Tsarists try to take Finland and Poland.
Unrelated Side note:
So from what I can glance, it seems that Kaiserreich devs are somewhat aware of a common critique I've seen from various people: that their mid-game and end-game is very bare bones due to all the exciting content drying up by the time the war starts. And this could potentially be seen by the reworks they are seemingly focusing on.
Remember that India rework on indefinate hold due to their dev team being moved elsewhere? Turns out it was because the KR lead devs has come to the conclusion that they need to lay the groundwork for the major WK2 players(UoB, France, Germany, Russia) first before working on the rest of the world
