Yes it would. That's an interesting solution, but it puts you at the mercy of the white balance of the ambient light. i.e., indoor incandescent lights are horribly yellow, fluorescent lights are green, outdoor shade is blue, etc. This is easily corrected by shooting in RAW format and adjusting each image, but that's an extra step for you after the fact, on the computer. Also it adds a lens element (or several). All lenses introduce some amount of quality degradation. A flatbed scanner has no lens and provides its own calibrated light source.
