Sounds like a lot more work than it is worth to me. Savings would be very small, if any.
Easier to just resign yourself to packing along a cleaning rod and a milk jug of water based cleaning solution. On the rare occasions I shoot corrosive, I put about half a cup of Murphy's Oil Soap and a couple of ounces of water soluble oil in half a gallon of water and and use that to scrub before my normal cleaning procedure. Never had any problems.
