First the good news:  Vuescan software will drive the Minolta Dual scan
mechanism beyond the normal required for 35mm scanning, so the firmware
does not seem to have placed an artificial limit on how far the motor may
be driven.  

Now the bad news:  The hard stop for the Dual scan in only slightly beyond
the normal limit.  The internal architecture would need to be modified:
longer lead screw and guide rods.  The point where these components are
mounted (where they would need to be lengthened) is quite near to circuit
boards at the read of the unit, so the case might need to be lengthened...

I think it could be done if one were sufficiently motivated though.

If anyone is interested in tackling it, let me know.
