Building keeps onto walls

In some castles keeps were part of the wall I think it would be nice if you could build keeps on top of walls similar to the way gates or towers are built on walls. It would add more ways to build defensive walls or to create an aesthetically pleasing or historical recreation of a castle. it would also add more thought into keep placement putting right on the wall could help with defending the wall especially against ranged siege but since its also more exposed it can be destroyed easier.


In Battle for Middle Earth II you could attach walls to your fortress. I think that could be a cool mechanic in this game too for Keeps.


That would be a neat feature, as for now to get decent coverage I have to build my Keeps as close to the wall as possible.
