If you scaled the item by using the scale channels, then you can make a pose file that you can distribute so that others can apply the same scaling. Get the free utility Mat pose Edit. The basic idea is to save a scaled cr2, load it into Mat pose Edit, delete all channels except for the scaling channels, then export a pz2. If the scaling is implimented through morph targets you can still use a pz2 to inject the morph the technique is called delta injection, or morph injection, I don't have time to explain how that works at the moment sorry.
