I think you may be on to something, Broadwaychild.
Queen already has stage experience as a music artist, and she has acting ability, so perhaps the stage might just be a possibility. I wasn't crazy about the pieces she performed on SNL this evening, but I know she has a great voice. This was first evident to me on the "Living Out Loud" soundtrack (I believe that was the movie soundtrack she first sang on. Correct me if I am wrong.)
