Switzerland is small. Adapting its system for a bigger nation blindly might result in something like Turkey.

But I've just refreshed my idea of its system and it's similar to what I'm describing, yes.

The main difference is actually that Soviet system had a few levels of councils, the lower level electing the next, while in Swiss system there are three levels all elected directly.

We know for sure that Stalin abused that property to gain power. And one can argue that Yeltsin did the same before dismantling it.
