Large Premium City Map

One of the main things I would like to do with Inkarnate is create a very large city map, along the lines of King’s Landing or Oldtown from Game of Thrones. But I’m not sure if that’s possible with any premium assets, from any POV. I don’t mind creating the map in pieces if that’s required but I really want to know what’s possible. Obviously I wouldn’t be asking for any help with Adobe, but how best to line things up would be awesome. The population would be 250,00+
