Well now that was one of my questions.   How much weight does a=
 spring represent, for instance in the sustain pedal lever?   Any=
 hoo, I'm going to experiment on the next pedal retrofit coming=
 up.   I'm not sure lead weights are more of noise maker than=
 springs?

The only one that comes to mind, is that magnets lose their=
 properties/strength with time.
As for the lead thingee: you'd have to put one helluvalotof lead=
 into the system to mimic the effect of a spring, which is what=
 pianists are used to. Perhaps making the entire system out of=
 iron or steel would come close. But, still not the same sensory=
 for the pianist. Also more propensity for noise. :-(
Just my inflated $ worth.<G>
