If you like the individual blocks, why not separate them and set them with an alternate block, either just fabric ( your choice of color), or pieced?
This is why l use a large design wall...blocks go up on there , unjoined, and l take a photo. If l don't like my setting, l can add sashings, blocks, drop set...anything. l take photos of my attempts. Later, over coffee, l review and often have trouble deciding between two front runners!
