Hey these exist.
Unfortunately, while they ARE bricks, they don't really meet my standards as a releasable add-on. They require a floating bricks script which is in the bad add-on cache. But hey! If you have a working copy like I do and/or just want them so you can stare at the pretty ghost brick, feel free to pm me and I'll send em to you.
They are 1-way single plane bricks I made for a crouch-race type dealio. I have them set up so I can place them inside of other blocks, but unfortunately this means unless you break some key functions of the game you will always get a float error when trying to place them.
The print on them is a custom ModTer texture. I can send that too if it tickles your fancy.
