You won't be able to replace just the trim. I'm sure it's on there pretty good and if you were to take it off, either the glass would come with it or it would break the seal and you'd have dust under your screen. Also they locktite the screws in there pretty good. I tried taking them out once on one of my Droids and it felt like they'd strip out before coming loose.
There are a few things you could do.
1.) If the scratches aren't through the black finish and into the aluminum, you could polish them out with some paint polishing compound.
2.) If the scratches are through the black, you could mask off the glass and the rest of the phone and take a scotch brite pad and remove the rest of the black and then polish the aluminum to a mirror finish with Mother's polish. I have thought about doing this myself. It would be easy to do and would look awesome. If you scratched it after that, just get out the metal polish and fix it.
3.)Just put another case back on it. The body glove one looks nice.
