You would probably have to use the bullets without the plastic tip to shorten length. But still not sure if the length of all the bullets (with the rear bell) would be less than twice the diameter. As I recall, copper is lighter than lead so that would make them longer. Email the bullet maker and ask what the length of each bullet is, or bigblock can probably measure some for you.
