Would it have been plausible for Russia to avoid the Bolshevik Revolution during WWI (for instance, by having Kerensky side with Kornilov instead of arming the Bolsheviks) and then to expand so much over the next several decades (into Xinjiang, Afghanistan, Persia, et cetera--possibly as the result of a new, post-WWI war with Britain) that its population would have eventually (due to massive Muslim birth rates) become either majority-Muslim or close to it?
Also, if so, what would the consequences of this have been for Russia? Indeed, how would such significant demographic changes have affected Russia, Russian culture, Russian society, Russian politics, Russian policies (both domestic policies and foreign policies), et cetera?
