Eh. The Tsar Nicholas was pretty hated by the time of his abdication. Had a white warlord rescued him, they wouldn't have restored him, rather just used him to help themselves be Tsar.
Likewise there were not shortage of noble whites to make Tsar with the family gone, had the Bolsheviks been less successful.
I'm team better scenario would have been trial and execution for Nicholas. Rehabilitation for the rest (under close scrutiny in Siberia).
I mean the best situation is if you can do a Puyi like the Chinese, if only so fuckers aren't complaining a century later.
