What do you mean that the two 5p windows are not very far apart?
 The aperture openings of the Realist format cameras are 71.2mm
apart.  That's plenty far apart.  You can open the interior of
the apertures so that the film gates remain centered.  By doing
this you sacrifice the ability to "sneak" two images between any
given pair.  You can only fit one so you need to modify the
advance sequence in a 1-3-1 type and you will only get 19 pairs
in a 36 exp roll, instead of the usual 29.
