I'd like to see maps with thematic "kingdoms" of indies that could be taken to the point where they are rudimentary custom nations (ie modded) nations. An indie kingdom would have five provinces, one central province with a castle and all that and four surrounding provinces. They would be very tough to tackle on indie scale but the reward would be a castle and their "starting site". If taken to the point where they are custom nations they could even fight back...
...a less extreme one would simply be a map with a lot of custom content.
I think there was one a Dom 2 map that took one of the preset maps and made it so that players started with a small "kingdom" that had stuff like pre-found magic sites thematic to the nation and some extra commanders and such....pity I forgot the name of it. It was great fun.
