Mock up of proposed front bumper

So, I had an idea last night about what I wanted done to the front end of my car, and decided to work a bit of photoshop magic to see what it would look like.

So, below is a mock up of what I want to do. I think it looks pretty good, but what do you guys n gals think?? Also, would filling in that gap at the front cause my engine to run a bit hot?? The bit down the bottom will just get painted black to hide it a little.

What I want:



Not entirely sure how I will make it look like that yet; fill it with fiberglass and bog perhaps??

Any input is appreicated
