On top of the mechanical issues, CRT glass also functions as x-ray shielding, for which reason it is leaded (Pb). You can't really make that part lighter.

(This isn't really an answer to the overall question—just a narrow observation of interest).
This is an interesting point. Does anyone know how much lead would be in a 21 inch monitor?
According to [0], about 1.2 kg (2.6 lbs). Surprisingly this is mostly in the neck and funnel of the tube - the screen itself uses different metals because lead would affect its optical performance.

Oh I didn’t know that. Neat.
