I had an Audiodkarma Pro Cable Cooker, what early last year, thinking of doing the same thing.
No one was the least bit interested. Funny, all of us believe in cable break in but no one wants to pay for it.
I sold it, actually exchanged it with a cable manufacturer.
My findings, break-in works better when you go immediately from cooker to equipment. Re-handling and mailing out definitely affects the process and lessens any benefits.
