Yeah I wish they took the NWN framework but made it turn-based like the old gold box games, and even stringing battles/skirmishes together on a world map with nodes like FF Tactics does, would be awesome - and make sure to allow 3D spaces and mounted combat (like FF Tactics)... imagine being able to fly around on a griffon in battle and rain arrows on your enemies in full turn-based tactical glory!
A basic campaign would be a map like the Kingmaker campaign with a bunch of nodes that players can explore, but adding a kit that let's people upload their own maps, generate nodes and add in scripted battles and random battles... even on that level I think it would be extremely entertaining.
