I wish you luck with it. I'd also like to say that I was by no means attempting to discourage you when I started discussing the over all size of the city itself, just making a note since I suspect that most people, such as myself, have never taken the time to actually look around the city and think of the scale of it. As you said, it would probably be best if you ignored actual scaling when it comes to placing Foundation in relation to the upper city, at least until, (if there is an "until"), we get to explore the inner city.....

I'm very much looking forward to seeing how this project of yours unfolds, and will definitely check back in this thread from time to time.....
