I hadn't thought about aluminum stair nosing. That may be the ticket. I could get cheap Sam's Club laminate like I already put on the landing, cut pieces to fit both the tread and the riser and then cover the nose with aluminum. This would avoid having to cut off the existing nosing to put wood or laminate nosing in its place. Quick, visually appealing, quiet because the laminate has a foam backing, and inexpensive. And if anything happens to a tread it is easily replaceable. I like it.
