For the parts you're talking about, probably. But, that's just me. plus, you don't have a lotta choice.
It really depends on your tolerance for mismatch, and where the mismatch is. On my last build, I used a custom-made brass bridge that I thought would match up with gold parts fairly well. As it turned out, I wasn't happy. The difference was too profound. So, I had some custom brass parts made to replace the gold parts. Again, the difference was too much for me. As it turns out, brass varies in color according to alloy ratios. So, I cursed the gods, as I am wont to do, and did some mixing and matching to get things to appeal to me.
If parts are close together, it's easy to see a mismatch. Farther apart, not so much. For instance, I still used gold tuners, but they're far enough away from everything else that even I don't see the mismatch. Also, there's such a thing as expectations. That is, if you don't expect parts to match, then it doesn't matter if they don't.
If I was going for a creme accent instrument (and I am right now with my L5S), I'd do all creme parts and damn the torpedos. If some things don't match, it's entirely likely I'll be the only one who notices. If by some freak chance anyone else notices and gives me grief about it, then I'll tell them to eat shite and build their own guitar <grin>
