Violent and Democratic Revolt, Proxy Wars, and Espionage

I've played 13 hours of Endless Space and am loving it. It's got that mix of empire management and external affairs I've always longed for. I have a few suggestions to expand on that internal and external management.

There should be the possibility of straight up violent revolt if a system is unhappy, or perhaps due to the meddling of another Empire. Maybe led by a hero?
Or, on a larger Empire-wide scale, sudden political unrest due to an event, perhaps resulting in the formation of new, maybe extreme and popular, political parties.

Likewise, I think too much of one thing should lead to the rise of the other, e.g. perpetual war might eventually lead to a rise in the popularity of the Pacifists, or over-industrialization may cause a surge in the ecologists.

I also want to be able to pitch minor and major factions in wars against each other, and back them up with resources specifically meant to be used for the war. And, while we're on that, maybe additional ways to direct allies during a war?

I also think it'd be really cool if there was some kind of espionage system, to reveal info about enemy planets, fleets, politics, and meddle in those affairs, perhaps by supporting certain political parties.
