I could see this working with the right artist.
*Red* white blue, and then for the ducks green brown blue (depending on the type).
I'd be less worried about the colors than the amount of imagery/number of images. Generally less is more. But I could totally see a flag rip on the upper arm, and a duck/water OR baseball scene on the lower. All three on one arm (if I've read you correctly) seems really difficult.
Everything's down to finding the right artist though.
