If using the seam ripper has you just .. wanting to toss it back in the box. Consider slicing down the centers of each of those wide plain stips , leaving only 1 inch on each side. Insert a new row of ... something like a new row of stars in colors that would compliment the others.
I would also cut down the border fabric leaving only a very small amount, and add some of the new fabrics used in the addes stars.
If you don't find a solution sell it as many long arm pros are looking for unquilted tops to practice and then donate.
