I think you'll find that putting together a quality small to medium sized scenario challenging and time consuming, which is probably why you don't see a ton of really massive ones in the 10 years SB has been in existence. Keep in mind that Marc worked on the Stalingrad stuff on and off for the better part of the last decade.
My suggestion would be to play around a bit, start crafting some stuff and see if you can put together the massive type scenarios you're looking for. The entire map of Hue is available on VN, so that would be doable in the regard that you don't need to try to create a map. Some of the ones you're listing don't exist, and since there is no true map editor, would be impossible to re-create.
