Idea for interior mod. JonM?

So here's what I want in my black interior of my Alpine White M Coupe (which I bought mainly because I thought RonS was my hero.)

I want the three little motorsport stripes on the E36 M3 seats. I want them at the topish corner of my black M Coupe seats. There are seams on top and bottom to accomodate them.

Pipe dream? Would the entire seat covering have to be removed to do? LeatherZ leather experts advice needed!

Oh and I want a traffic pro. If anyone has an extra please send it on.
