re: Box clamps box

At the risk of sounding stupid, has anyone ever thought to perform this exercise where, after finishing the joint, you only cut one of the two boards, then dovetail the results perpendicular to the new cut-off? Dovetail stairs! The strength would probably be questionable but you would have quality A at one end and quality B at the other, hopefully showing marked improvement between.

ASIDE: Hey, I said “at the risk of …” — I realize that this would pose a minor clamping/working challenge
