It would work Fine Katrina the expensive bit would be the mirrors. you will need some rather large ones to gather enough light to beam it into your house. but then if you are going underground you will know already the prices of doing so.

Maybe even if a person had to buy them new, they might cost less than a "wall" mirror. Many wall mirrors are not 'optically correct' these days, they are cheaply made have bad reflections, like something out of the old carnival House of Mirrors.
