Sure, altho you may need smaller / more accurate grads to measure things out with.
What I have done with this kit (before Rollei took to distributing its Digibase C-41, which is just Fuji repackaged) is mix it up for one-shot use. With a Jobo processor, you only need 170ml for 1 roll of 120, so I round up to 200ml just to be safe. 400ml for the 3x120 roll tank, and 500ml for the 4x120 tank. Even with the import cost into the U.S., I still can come out ahead of any local lab, with perfect reproducible results.
Just make sure to keep the Part C refrigerated or any air removed from the bottle for longer term storage - it will go bad within a few months after the seal is broken (long before any of the other components).
