I myself have been thinking of things similar to this, although a bit more simple. I agree that some form of system for allies would be beneficial but admittedly I get a bit overwhelmed at all the bonus and pen stuff. Personally, I would just be happy with a 'friends list' of sorts for allies/enemies that would notify an ally if a war has been declared against their counterpart.

I also had the interesting little thought of being an ally automatically includes in you wars. Mass hysteria would ensue but boy would that be fun to watch!
