Audiopanda, it seems you may have an ideal situation! If your cables are long enough to get double runs if cut, simply send them to the mfgr. to do the job. Most cable makers will do such work for an agreed upon/set fee. It's WELL worth it as opposed to buying additional cables! And, if the cable maker does the work you are satisfied it's done cleanly. Perfect!
It can be a real PITA to work with the conductors yourself. One of the first times I obtained a brand name speaker cable was about 20 years ago, and it was a pair of very long Audioquest speaker cables. With fear and trepidation I cut them in half and finished the ends. I didn't reterminate them, but had to strip all the small conductors - 96 total between four unfinished ends - and twist them together. My hands were sore from all of it, but it was well worth it! If you do so you will have a harder time selling the cables as they are not reterminated, but you also might have a second rig to put them in down the road. :)
Wig, hey, shoot me an email. Yes, double cables is a glorious thing, is it not? :)
