You can always try it. The entire roller assembly simply comes off with a gentle pull from the inside-side. If two are the same size (which they should unless Polaroid really wanted to make things complicated), I would try the switch.
You can check the Colorpack 3, Colorpack 4, Colorpack M6, Colorpack 5, Minute Maker, Square Shooter 2, Square shooter 4, Super Shooter, Super Shooter Plus, The Clincher, The Colorpack.
These are all American models equipped with rollers which should make it easy to pull.
