I think I understand what you're thinking, but some of the things you're talking about aren't rare, they just simply didn't exist.

For example, the orange houndstooth interior wasn't around until 1971, and therefore not possible on an SE in 1970.

There were orange longitudinal stripes, but again, not until 1971. It's a neat idea, but I wouldn't combine options that weren't even possible, or for a different year.

For me, it would be all about the colors. With the V9* painted stripe, the possibilities for a 70 Challenger are almost endless. How about FE5 with a V9Y yellow stripe, and a red interior, or EB7 with a V9V orange stripe and black painted top?
