I think you if you find the sound too intense, you should do something to make the magnetic field more tolerable, like have a spacer in-between the contact points, wood, paper, cardboard, non-magnetic metal. something to try while your at this
from my understanding, the stronger a magnet is, the harder and more metallic it sounds, if you can weaken it, it'll give a softer more mellow attack, with less presence.
I think this will be a pretty hard job to get desirable results off the back, but if you mess around for some time, you could find yourself with something decent...... hopefully!
