Unequal cable lengths for home theater????

I have 7 speakers and a sub in my theater. Each pair of speakers has an equal length pair of speaker cables. I was re-doing some other wires, and I noticed that I could really clean up the rat's nest behind the big-screen TV if I didn't have to worry about equal speaker cable lengths. All of my cables in the theater are home made Canary cable and WBT connectors, so I can easily make changes. Will I be sorry if I do this?????
