What about detailed sub maps of regions? showing the overview of the city/region, with temples, guilds, RCS and any other building that are able to be build in game, but now as a lord you could decide where to place certain buildings, and the way your city looks.*
It doesn't have to have any effect on the game at all, other then just the way stuff looks for people.
So now you don't see the buildings on a list, you actually see them on a map. (imagine a city build in imagine of the blood stars or some other religious or national symbol...)
*to a certain extend, I understand that it could take lots of work to make a city map fully customizable by it's lord(including streets and all the regular houses, how there aligned and where there placed).
Considering all the projects that are underway that actually add to the game play. Something comestic like this, in a game that is largely text based, would probably not be a priority. Besides we would need someone to actually draw all those images, and then need to spend time either coding a complicated DIV or Table grid arrangement for them or a canvas sprite engine, handle all those annoying things like z-drawing orders, overlapping images etc.
