With the center of the hood being fixed, it kind of makes sense that the center divider is there. It kind of continues the lines from the hood down the grill. If it was a one piece hood, the single grill would look fine. Maybe you could play around on the computer with different designs and see what you like best.

What would be interesting is if you could make the center divider removable and build it so it fits on top of a one piece grill. Then you could change the look whenever you wanted to...just by removing or installing the center piece.
