I keep getting a mental picture of a whole scene (landscape type) on a solid or indistinct design background with borders around it. Maybe even hills and valleys appliqued to provide a setting for your figures.
Or you could do it like window panes or a slide show with each of the figures in it's own maybe 12 inch square with sashing between....maybe make the sashing out of small squares of coordinating prints that would have the colors you are already using.
