Hmmmmmm. From the fabric on the left, you could make rectangles that highlight the important motifs (perhaps a bit of fussy cutting?) and then "frame" them using the fabric on the right. For added interest, you might add additional borders of red, white, and blue. (Think: matting around a framed piece of art.)
Another way to go is to make a "6 Hour Quilt," pattern by Kaye Wood. Since all strips are cut 6" wide, the pattern on the fabric isn't terribly obscured. You could use both your fabrics and supplement them as needed to achieve your desired finished size.
