Yeah, we are thinking along the same lines. I was going to pretty much go about it the same way. I like it a little on the darker more purplish / blue color so im going to test a couple of different pieces. i have some orange clear plastic sheet that works well so i will try adding some blue tint on the back to see how that turns out.
and yeah i do like to build most of my own stuff too. i had Dan/ YHR build his battle system into my tank with the Benedinni sound card in it and this thing just roars. It sounds so good with the real turbine engine sound I love this tank.
