Tension's easy, increase wire size. With low tensile strength 
re-bar you likely just trade one tonal problem for another, 
but hey, you might dislike the new problem less.

The fact is that these pianos are just really bad scale 
designs, and aren't going to be "fixed" without moving 
bridges. Even then, doing it right would take you back to the 
drawing board.
