Idea: Double monarchy in Russia (proposal)

Russian democracy is doing ok... but not as ok as it could. why? cos it's such a huge country with so many diverse cultures and interests... so in the end nobody is really 100% satisfied from the proccess of democratic decision making. So... oligarchs are ruling in modern russia.
besides (if you look from historical perspective) russia has been always more productive (from political and economic pov) when it had monarhy. so i thought, why not to combine both - democracy and monarchy - namely to have 2 monarchs instead of one?
they could compete with each other (just like political parties do)... and to be true to the cultural roots at the same time. (yes, russians always liked their monarchs, unlike the communist rulers)
