Concerning the hardware issue I might try to find out something in the
Epson manual ... The slide and film holder which came along with the
scanner gives you the possibility to adjust either naked film strips or
a couple of framed slides in a row - no spacer for adjusting the
distance. I was already thinking about getting myself such a spacer - it
just needs to be 50*50 outer dimension, 36*36 inner dimension and 1.25
mm in thickness, but it must be good in flatness, and that's what I'm
worried about in self-manufacturing :-)
