If the plate around the GT emblem does have some "pitting, scratches or outside dents", would it be possible to buff/polish it or to apply another technology to make it close(r) to mint?
Don't wanna glue on a NOS or repo plate.
Don't believe so unless you can figure out how to remove a consistent amount of face material off the whole surface, tapper the dome so it does not become noticeable and figure out a way to return the original pattern/texture to that surface
Might be doable - just don't know how one would do it and if (other than a sense of accomplishment) it was worth the effort.
As for refinishing and replating the whole thing people are doing it. Just hasn't been me - though I have seen the positive results on cars judged
