I would have to say nay not because of how I think it'll look, but because it'll ending up costing more than what you're actually planning.

Adding a widebody kit means more body work. More body work means more labor. And more labor means more money to put it on and paint it. But it doesn't stop there.

Having a widebody kit means you'll need bigger wheels. Bigger wheels means you'll need bigger tires. Bigger wheels and tires, means more money.

Not a lot of wheels with a 4x100 bolt pattern go that wide (probably 7.5" at the most). For you to fill that wheel well with wheels that sit flush to the widebody fenders, you'll either have to special order and have wheels made, or use spacers.

So if you have the cash to pull this off and make it look good, then go for it. Otherwise, I'd invest the money elsewhere...
