I've suggested that Cities/Ruins/Towers placed on terrain provide that terrain bonus for units (as it did in DLR). So a tower placed on hills would provide in addition to the wall bonus, a hill terrain bonus. Thus attacking Giants/Elephants wouldn't be denied their bonus just because a tower was built.
I also think Towers/Ruins/Temples shouldn't be considered as Cities in terms of bonus's. The City bonus is already plenty good enough without coming into play in these areas. I'd suggest that Ruins are considered as their own terrain and Ghosts get a bonus there (as well as any other future Undead unit). Archons/Devils/Demons could get a bonus on Temples for being Celestial creatures (because Temples could be devoted to good or evil, there is no distinction hence why all 3 get a bonus there). Towers I wouldn't consider for any special bonus at all other than the walls and the underlying terrain.

P.S. I still think erecting towers anywhere will be badly abused. I'd definitely have to edit Bullrun to make all those mountain passes 2 wide instead of 1 wide to prevent them being clogged with tower followed by another tower. Other maps have this same problem where 1 tower can block a whole section off quite easily thanks to mountains/water nearby.
