What a cool idea. Definitely go mirror-lid! But would you be able to get purity with the tube facing up, or would some magnetic engineering be needed?

If you do go mirror-lid, you will need to reverse the leads to the yoke's horizontal windings. Otherwise, the picture will appear backwards reflected by the mirror. If you look directly at the screen of a working TRK-12 while standing in front of the cabinet, the picture appears upside-down. The vertical inversion is corrected by reflection from the mirror, and the horizontal reversal is corrected by the polarity of the yoke leads. Oh, those clever RCA engineers of the thirties!
