I know how to fix it. Just add the body kit; problem solved.

Seriously, you'd need to repaint the trunk after plugging up the holes, and thats alot of work. Take the following for what its worth, but swapping trunk lids is a no-no also. The body panels have the VIN's on them, and youd ideally want them all to match. If you plan on keeping your car for a looong time, and not trading it in at a dealer, then its a mute point.
