hi toadmen

have you considered just setting the lens up for hyperfocal exposures
from what i remember, schneider lists the distance + fstop on theirwebsite
so you can just use it as a fixed focus camera ...
have 2 backs .. one with ground glass ( or whatever it is you are going to view through )
and have it the same distance from the rear element as your film / paper plane...
you have 4 pegs and 2 large elastics to secure the back on it, you remove the back
slide the paper holder / film holder, secure it with elastics and you are good to go .
if you can deal with longish exposures since hyperfocal is usually stopped down a bit
that might be another option.

have fun !
