Recreating maps will most likely not going to happen. Maybe changing a region type might be possible now that Anaris has all the maps. I think he mentioned something about hating doughnut regions and wanting to break them into multiple regions? I might be confused with someone else however.
If he can do that, maybe moving some mountains and moving some cities around should be possible as well. Wish Dwilight was more of a circular shape like South Island. AT had its issues as well mainly due to the bottom part protruding out. Plus it was also a long map as well although broader. I guess Tom was a big fan of long maps.
As for your dynamic demographics, MF does exactly that. Maybe you might like that game. I believe it is not possible with BM unfortunately due to how it was designed in the first place.
