Your question contains the answer: "не смогли полностью охватили идеалы Майдана". Their idea of democracy is nominal and limited to elections. The idea of being accountable to the public is as foreign to them as it is to the government. They are in an unenviable box between moderating public desire for action, avoiding escalation, and being forced into a diplomatic process all the while preventing revolutionary leaders from emerging. Besides, any emergent leader would have to escalate or quickly lose public support if he dithers, so it's doubtful that anyone would do better within the same box.

You don't actually think that the opp could prevent a true leader from emerging or suppress useful ideas? The stage may be important, but in the age of social networks, online streaming TV, crowd-sourcing and crowd-funding it's not at all critical. Most effective and interesting Maidan's initiatives were done without significant opp support. Public hospital comes to mind.

As to your own ideas, no one may pick them up, but in the modern world, appealing things tend to propagate horizontally by osmosis. Arestovich is a great example (regardless of his personal motivation). All he did was skillfully express an idea that's appealing to the public at large. It may not be implemented in a centralized fashion right now, but if the push comes to shove, it will be done on an individual level.
