I looked into doing some changes to the center console on my KC way back when I bought the truck in '06. I wanted to add the rear vents which the KC didn't come with. I don't remember there being any real differences between the two. IIRC, you could actually order the ducting for the AC and the back piece of the console with the vents. My point is, I don't see why you couldn't swap one for the other. I don't know about the DVD. Can't speak to the overhead question either.
