That would be cool, I would design and plaque shaped like Metabees back. But I don't think that can be done, unless you split up the parts.
-Lever (would be cool if it had felt)
-Front plate/lid, but with a cutout for a window
-And clear plastic window that you can put into the lid
And you could base it off of this, and what Metabees back looks like. If you want me to, i could find a better reference picture, this one seems off.
