I would leave them alone as the first shot of the guy is diect flash and the other is balanced with the available light better.
Who would worry that the shots have different color bal. when its shot of different people with different equip used different ways.
They both look fine, the 2nd more natural.
Whats the big deal?
I've been shooting long enough to know NZDoug is right on. To make the two look the same is going to be extremely difficult, because flash being the key light source in the guy's photo won't match the blended light source of flash/ambient light of the picture of the bride. Even getting the colors close still won't make them look the same because of the direct/indirect flash techniques used between the two photos. Instead of letting the customer dictate how you should process the image, I would explain there were two different techniques used when shooting the two shots and they won't look exactly alike because of the difference in light sources.
Alot of times explaining this will often resolve it or suggest turning it to B&W for a better match. Suggest possibly picking two more out, as I'm sure she's got plenty to choose from.
