A reactionary, non-communist Russia seems like the logical stand-in. Germany's unique conditions come from the combination of an industrialized, largely catholic West where democratic parties (SPD, Zentrum) were predominant, and a more autocratic, agrarian, and protestant society in East Elbian Germany/Prussia.
Pre-1914 Czarist Russia is like a giant version of East-Elbian Germany with all of the German Empire's condition's cranked up to 11 (landed nobility establishment vs. large left wing party, no tradition of liberalism or democracy, chimeric combo of Empire and national state with social conflict between state-forming people and ethnolinguistic minorities.
Ethnic Germans from the Russian Empire, as well as ethnically Slavic reactionaries had a disproportionate influence on the early Nazi party.
The Russian Roots of Nazism: White Emigres and the Making of National Socialism, 1917-1945, goes into the connections. The
Aufbau Vereinung (Reconstruction Organization) brought together White Russians and early figures in national socialism who wanted to establish reactionary regimes in both Germany and Russia, dominating eastern Europe through an ideologically compatible Russo-German alliance.
Max von Scheubner-Richter, the brains behind the beer hall putsch (he was shot while standing right next to Hitler) and Alfred Rosenberg, NSDAP minister for occupied territories in WW2, were both Baltic Germans who were born in the Russian empire. In a 20th century without a Bolshevik takeover, their antisemitism would've fit well with any Russian dictatorship.
Ethnic Germans were a disproportionately part of the Czarist elite and the landed nobility (especially in the Baltic states), so they would have economic incentives to join an alliance with a Slavic, reactionary/Anti SR movement. In any White Russian scenario post-WW1, Russia would a be former empire turned nation-state like Germany with oppressed co-ethnics to "liberate" from new countries in central eastern Europe.
The rhetoric of Russian nationalists nowadays about how Ukraine is just a made-up country and a puppet of the west is very similar to interwar German remarks about Poland being a "season-state" and a glorified French puppet established to keep Germany down. A reactionary, pan-slavic Russian regime would face similar motivations that Stalin did to suppress Ukrainian national consciousness and crackdown on the other nationalities of the empire as well.
