Bumper Swap

I hate when a trim level you want doesn't come with all the features of the next one up. So I've settled on the K5 EX as what I would want if I ever traded in my Optima. Actually going to the dealer tomo to discuss this year end savings event. I just prefer the GT-Line bumpers . Anybody looked into this swap yet? I know it would be more complicated than the optima was, what with the fog lights and whatever else.
