Eric,

Multisampling or better a longer exposure sampling + a normal scan 
stacked can increase the dynamic range and create more detail of the 
original densest film area.
It would be interesting to see the light source output increased for the 
same purpose, sensor noise will increase more with a longer exposure 
than with more light.
