Yes you can use 107, 108 etc with 4x5.
I have a Polaroid Graflok back that takes the standard Polaroid 107 or 108 film packs. It uses the Graflok Back for mounting, remove the ground glass and attach the polaroid back in its place.
It gives just the center of the image, and not full 4x5 size, but you get an idea of exposure and comp.
You might try to find one of these, there is no manufacuters name on my back, so can't point you to a source.
