Walls as Fences? Gates on Walls?

[wilcat74]

Does anyone know of a work-around or know of any cc/mods that allow building design to use walls as a fence -  so that I may use a gate on walls? I would like to use a gate on a wall (for all sizes of walls and still be able to function). Maybe, as well as to put a door on a half wall without the half wall trim going through the door. Help? Is there anything out there?

I've built foundations as wall in the garden by connecting to the house first and then placed the shorter iron looking railings on top as a decorative bit of the 'garden wall' then placed a gate using MOO cheat into the wall. This all works fine.
