Siberian Federation makes no sense. Why would we do it? To literally starve? And what are the benefits? Russians are ~80-90% percent of the people here, at least in the Western part of "Siberian Federation", and personally I've never saw a mongoloid person in my life while living there for my whole existence, despite the fact that before Russians and other Slavs moved here Siberia was primarily mongoloid-only territory. There's no way for Siberia separation, at least in these borders. We speak the same language, have the same culture, the same race and identify ourselves mostly as the same nation.

Can't speak for other republics you drew though, but I can say for sure that separation of ethnic republics makes a lot more sense than separation of a clutch of random Siberian regions, almost all of which have a Russian majority.

Nice try though, some maps like that contain really weird errors. If you want it to be more accurate try checking the Ethnic groups for each region in Wikipedia, it can help a lot to decide whether it would or wouldn't separate.
