I was actually of thinking of a very similar pattern for in front of the hood vent, but also doing above the lip angled in up to the grill (following the contours, making it much like the 1LE lip look wise). I have the wide black center stripe on the roof and hood deck, and about to put a mosaic black spoiler on, but the front still looks empty.
I think it looks pretty good. If I go this route, I won't have the thinner outside line, but I did the way you used them to align the outside part of the vent, and the wider ones with the inside.
