Hope this doesn't sound mean but I think you are missing the forest for the trees here. Now don't get me wrong, there are plenty of pieces of gear that if the dyeable parts were altered they would look better, but this doesn't seem to be one of them; especially because you are using the entire set and not just a piece here or there. The outfit needs to be looked at as a whole, and not just does this one part of this piece match this other part of this piece. Think of it as how you dress yorself, you don't not wear a certain shirt because a part of it doesn't match your pants, you wear it because the shirt as a whole matches.

That being said I do think you are right about the metallic accents they should be consistant. Even in real life no one mixes silver and gold.
