Castle style battlement half-wall, please.

I love building castle style structures. In that regard, could we please have half walls for the crude stone and obsidian tilesets that have the archer notches in them a.k.a. crenelations and merlons? The obsidian tileset currently has walls with archers' loopholes. Half walls with battlements like these would be a wonderful addition to the tileset. Thank you!
