Hrm. This could be interesting - if you want, I could have it so that the Pliyev Troika instead flee to China, and then potentially offer themselves as another option for a government after the Siberian invasion has been completed? Pliyev, Yeryomenko and Chuikov are all pretty hard-line communists, and would likely retain the support of a fairly sizeable chunk of the Russian Far Eastern Theatre - I estimated that the Russian Far Eastern Theatre would probably have been made up of between 24 and 28 divisions (based on relatively similar Soviet ORBATs from the 1960s in the area) and therefore they would maybe have been able to retain the support of 70-80% of the men under their command.

However, this is all subject to your ideas for the region. I can work with whatever, or I can simply relocate elsewhere if necessary.
