On a Cougar it would be right in place.
You know, kind of like a "Catwalk".
I didnt' vote, based on the fact you aren't done with it. As is, I'm not diggin'it personally. That said, it doesn't mean it wouldn't look totally bitchin' with a little more creative thought.
Try doing some photoshop stuff with driving lights, or black out work. You've put a lot of work into that grill. It would be a shame to ditch it without realizing it's full potential...or not.
Kudos on at least attempting something no one else has done. Kind of like a truck I saw today. 1970 F150 short bed with big old Cadilac fins grafted onto the bed. Very different. Perfect "Rat-rod" kind of thing, which based on the rest of the truck is what he was going after. Had to give the guy a thumbs up on pulling off something very difficult. He got a big grin as he drove by.
