Sorry, but my crystal ball is not working right now ... if you have the time and energy to take the photos, I am sure you will get a lot of valuable feedback.
You see, it really is hard to give suggestions, as not all 5-1/2" blue batik quilts are created equal. TBH, we have no idea whether this is just plain blue batik cut into squares, or if you have done any piecing, and they are basically blue with something else going on. Perhaps even, it is a printed batik, rather than a somewhat plain batik. Who knows?
Staggering for one, may be the downfall for another. There are other options to consider too, such as alternating with QST triangle squares for a totally different effect. So many options, depending on what you are starting with ... and the end-effect you want to create.
