Awesome work NYstyle! Glad I could help!
The silicone has held up just fine by the way, although, I did 'overlap' the plexi with it a little... so it's more like a rubber frame adhered to the wood than a true adhesive.
The only possible issue/difference with your setup is the light. I really hate my dual dome for the simple fact that I can't adjust the height of the bulbs independently, and with yours sitting on top of the ATBA you can't adjust the height of either, although I can't really tell from the photo what it's sitting on.
