Why not pop off the old hammers and rehang them on some appropriate shanks/flanges? If you factor in the cost of the knuckles, labor, it can't be that much more. Not to consider the difference in workmanship (not that you'd do a poor job of moving the knuckles, but probably not as good as the factory manufacturered thingees). I've done it many times and retain the sound of the piano with a big increase in overall performance. Don't forget you probably need to do some repinning on the old shanks/flanges...
