The problem is that Factorio doesn't support rotation on turrets. I can't make it a turret that depending on how you place it, it's facing a different direction. The only way to make it halfway good looking is to create 4 variants of the bunker, one for each direction (north, east, south, west). And then have the player decide which to place. I'd also need to make a conversion recipe for them for when the player needs ZxWest but has YxEast already crafted, they'd go for waste.
If that's ok for you I might do that.
