Adding a second center won't necessarily make that channel louder, it is usually done to help anchor the dialog to the middle of the screen due to less than perfect speaker/listener positioning.

As Adrian suggested if you want the center louder simply run it a few db higher in the speaker settings, many of us here do just this.
