On the surface (pun intended), glass mirrors sounds like a good idea, and I tried it some time ago on a 55 with FL lights. However it is the "glass" portion of the mirror that hurts- Assuming the glass is normal, 90% Transmissive, you loose 90% of the light going though it to hit the mirrored surface, then 90% of the remaining light on the way back out.
Net loss: 19% of the light, or 81% of the light gets reflected back.
Using plexi-glass mirror is slightly better, 92% in, 92% out = 85% usable light.
A good specular aluminum reflector gets in the high 90's for reflected light I believe.
