Honestly this is not the forum to be asking if you're looking to spend a bunch of money on exterior modifications. The prevailing bias here is towards making subtle upgrades to the exterior while improving the way the car drives.

Now if you really do want to get a Mugen kit, keep in mind that it will cost a ton. The bumper is $1080, the hood is $1599, the side skirts are $780 and the wing is $680. These prices are from King Motorsports, the official USA distributor of Mugen parts. There might be some shitty knockoff versions available out there but their quality will be reflected by their price and I would stay away. This would all be in addition to the cost of a JDM front end conversion.

Ultimately it comes down to whether you want to look at your car or drive your car. It takes several thousand dollars worth of investments to make significant upgrades to a car's exterior with any sort of quality which is why most people here tend to focus on making the car drive better first.
Not only is the CL conversion gross, but it's been played out since about 1998. It doesn't help that all of the options for going this route are made out of shitty fiberglass either.
