Scarf + brooch interactions

This is a meandering post that is not worth your effort in reading so apologies in advance. I've been thinking of getting the needles melty peace brooch to pin up a Kapital peace symbol scarf I had. I thought it was a cute idea but peace on peace started seeming a little matchy matchy. Private Joker's "born to kill" + "peace symbol" = "something about the duality of man" from Full Metal Jacket came to mind. I started looking for suitable symbols of war.
Apart from a vintage manhattan project pin the one what worked for me was a native brooch that incorporated an arrow. Seemed not too on the nose and denimhead / Kapital pieces vibe well with native jewelry. The question in all this is would it look good? Which is really the only thing that matters.
