I think silver stripes would look killer with your wheels. I'd take the spears off then.
My other advice would be not to think something is overdone because you see it all over online. I think I can count on one hand the number of Stangs I've seen with Lemans stripes in daily life. Also, since the GT350 and 500's have had them since say one, they are classic and never out of style in my view.
One thing to consider is maintenance. There are threads where people mention chips and how they're not fun to touch up.
