Some years ago, I had a bucketful of custom springs made for player unit 
valve blocks I manufactured at one time. As I recall, the cost for 10,000 
was just a tad over twice the cost for 500 - or something along those lines.

Or, different diameter front and rear bearing bars for each section, 
smaller in the bass, bigger in the treble. Then you'd only need three of 
the relatively more expensive grooved bar types, maybe using the outside 
trichord spacing for the bigger bichords. I wouldn't think the small string 
height change at the transitions would be a problem.
