I like the idea. I think you've put a lot of thought into this. I think it would be cool as an addon via a mod if it is possible, though I feel it's probably way too much of a conversion to make it work - that is unless someone has a lot of time on their hands. I don't think it's something the devs will do, since it's super far off on what the road map is. Basically, it sounds like you're describing an entirely different game.

I would probably buy that game, if someone developed it. ^_^
