Space platform tile transitions

[front]

Would it be possible to get the "under tile" transitions without having to use the space shader as the base tile on the surface, then covering it up with something so said shader is no longer visible?
I'm trying to trigger the "tall" tile transition, but it only shows up if the tile around it has the space shader, else there are no transitions.
I'm not sure if I fully understand what is happening here.
