Also, you can totally paint those regular panels. You could paint the regular panels a color of your choice and place them randomly throughout the space, and put your semi-transparent panels in the rest. Put like 30%-40% ceiling tiles in, and the rest in the corrugated panels. This way you at least save SOME of the sound dampening that the ceiling tiles provide, but still get the effect you are going for with the panels. I love the idea of the corrugated panels.
Also… instead of using corrugated roofing, you could use the semi-transparent drop lighting covers that are used for florescent lights. I believe they are the exact same size as your ceiling tiles, so they would drop right in. They come in a few different textures. I’m not sure they are transparent enough for what you are shooting for though.
