Multiple countries or regions in a loose federation is indeed a good idea.

The problem is that you would have to transfer power to legally established governments in those countries and in Russia, basically everyone who holds a position in any government function is a corrupt thug (not only in Russia, by the way).

You would have to restart things from scratch, like they did in Germany in 1945. Now that was a situation where several other big and mighty countries pushed for it, and in general the German population saw a need for things to change so they had a positive attitude.

In Russia, the effort to change things would be much greater. First, Russians are natural born pessimists. "And then it got worse" could as well be the first line of their national anthem.

Second, they have had a considerable brain drain in the past decades. It will be difficult to find qualified and honest people to run local governments. You have your elected representatives of course, but for each of those you need a hundred civil servants doing the actual work. Contrary to popular belief, that actually takes some brain power.
