I've got an old mini plan here. If you somewhat approve it I will start making it in real size, York.
I thought it was pretty much useless to start making something that maybe wouldn't get accepted in big size either.
The map is atm too big for what you had planned. So I would say I only would make the part with the yellow brick. I then would expand the part with the bridge and make a small indu area there. Not as big as the map shows.
A small prototype I wrapped up.
