This 6LE spoiler seems like exactly what you're wanting for the most part. If I ever get another Camaro and keep it this is the spoiler I'll be getting. It's just icing on the cake that it's on one of my favorite Camaros as well.

 

I think you can do this and make it look appealing by taking an inch of height off and laying it back a few more degrees. A spoiler should look like like it's functional, otherwise it will simply look like an add-on for the sake of putting something on your car. There's enough of that stuff in the aisles of Autozone and in High School parking lots.

It's a cool project. I really think that you can get it done in an aesthetically pleasing manner and am looking forward to the finished product. Good luck!

 

So after some tie.. i decided to sell the ss spoiler and the other lg motorsports spoiler... and got a 6LE AggreSSive spoiler and filled out the middle.. i love it... reminds me of the macho spoiler but taller

 

Looks sweet!
