Will you be able to do this and not create any dust/debris?? (I'm assuming you don't have one of those dust free rooms like a computer chip maker...)
Any time you handle film you risk the chance of putting debris on the film. You have to remove it, cut it, re-pack it, remove it again, load the holder... Not to mention the chances of scratches etc...
Seems like the cost savings you might gain would be offset with backup exposures and frustration over dirty negs...
Just my initial thought,
