Its doubtful you will hear any improvement from the shorter length. So the question is how much is the better looking shorter length worth it to you? Some place like the Cable Co will probably take your longer cable on trade and sell you the shorter one for next to nothing net. The other way, re-terminate, you spend a couple hundred to get to the same place but with an extra 6 ft cable worth maybe... a couple hundred. That's if you can sell the shorter cable.
The only way I see it worth re-terminating is Option Four: have them cut the 6 ft wires, don't terminate, and use them to replace some of the internal speaker wires. Probably not something you'll be into, especially with those hard to work on speakers. But I've done this before and its almost guaranteed to be a bigger improvement than any of your other options.
