Though, this may be worth experimenting. Lenses like the 127mm cover up to 6x7'' (inches, not centimeters!!!), the 180mm even 8x10''! If used at 4x5'' the results could perhaps be good if not awesome.

You will have a hard time firing and cocking the shutter, though! The pins which control shutter's operation would be INSIDE the camera's body.
