This thread is indeed interesting, so I'll just throw my 02 in.
1.) Its your car if it makes you happy go for it.
With that said.
Putting 40th anniversary emblems on a "non" 40th anniversary car ranks right up with putting cobra badges on a non cobra, gt emblems on a v6, putting si emblems on a non vtech civic, stuff like that
And body parts are in another class, most people don't add a mach 1 chind spoiler, and add a mach 1 emblem to the rear of the car.
