Was there an unbroken line of succession to the Riurikovich line? (Through which one of Ivan the Terrible's sons? Ivan and Dimitri both had some chances of surviving, and Fyodor could sire a son). Or do you butterfly away the great hunger of 1601-1603, and let Godunovs' rule continue? Alternatively, you can abort the Time of Troubles by keeping False Dimitry on the throne. But in each and every of these situations there would be different consequences, at least in short term.
