You would then throw away all the battery life advantages of eink. The way LCD technologies work as that when no electrical field is applied, the
Crystals suspended in
Liquid are oriented randomly, blocking light from passing through, making them opaque. When an electrical field is applied, the crystals align perpendicular to the surface of the screen, allowing light to pass through. Therefore, for an eink display under the LCD to show through, the LCD panel would have to be switched on (and constantly drawing power) at all times. And surely would cut down hugely on the amount of reflected light reaching and bouncing back from the eink display to the outside.
