Boys like quillows- they enjoy doing the folding and stuffing. I've seen circular playmats laced with rope that draws up to make a sack. "Transforming" items are loved by boys. An I spy quilt? A quilt with superhero fabrics? Snuggly fleece on the back. The previously mentioned cape idea is terrific. I saw an idea for making a sleep mat from pillows- might have been on Martha Stewart. A Long length of fabric divided into pillowcase segments to hold regular pillows (removeable for washing) that folds up. I'll look for a link. Don't set the bar too high- the boys have a lot of growing up to do, and they'll Love a quilt.
