@SmashKAB Here, this is a quick and crude example to show you what I'm talking about. I didn't bother creating unique objects for the layers--I just used a shader to speed things up. You can see the transparent pixels at the bottom of the images. I also used a solid-color tile to fill in the rest under that. I have snap to grid on in the capx to make positioning easier.
Anyways, here's a quick capx of what I'm talking about. (uses C2 218)
And here's a live version of it to run/test in your browser.
