    I don't think the wedge will kill sustain, though it might make it softer. Hold a tuning fork on a rigid steel table and it will continue to vibrate for a long time.
  It looks like a felt mute, so it probably wouldn't couple the beam and the soundboard much. The springs might add stiffness, but the board could still vibrate because of their flexibility. (At least, I imagine that it could.)

  I've been known to resort to measures like this, except I did such stuff on pianos much worse off that this one. Open cracks, big noises, no money, that kind of short crummy grand.

  Haddorff ... I've liked the ones I've seen. Also I have a sense of connection because my grandmother, aunts, and cousins lived in Rockford, IL where Haddorffs were built. In fact, my uncle's grandfather worked in that factory.
