I was laughing at the idea of men wearing quilts as capes, then realised that my ex used to do that with the sofa quilt when he wanted to sit at the computer on a weekend morning and couldn't be bothered to get dressed. The quilt was 60" square and the man was a slim 5'10, if that helps!
It's a lovely quilt which could appeal to anyone of any age and any gender. Men are as individual as women are, and have different tastes in colours. The colouring of that particular quilt would appeal to someone who likes red, and who likes bright colours. Find out which colours he likes, and whether he'd like brights (which it's beautifully suited to) or more muted colours. I really wouldn't use plaids or old-fashioned fabrics, it'd wreck the quilt. This quilt is about luminscence, about getting colours to glow together. It'd be best done with batiks. Some should be lighter and brighter, and some should be darker and more muted, in order to get the glowing effect. You could just as easily make this quilt with blue as the main colour, or green, or purple, or possibly a very dark colour such as shades of dark brown or navy. If you make it darker, just make the other colours a bit darker as well, and you'll find that they stand out more against the dark background. Let's say you use dark blue where this quilt uses red. For the other fabrics, you could pick a combination of red, turquoise, lime green, and marigold (orangey-yellow). Perhaps purple as well. That'd be more muted, but still fun, and certainly wouldn't look girly. Here is a fairly bad photo of a quilt I made for a friend of mine which is more or less those colours, though not quite the look I'm envisaging here.

I think young people, both men and women, are more likely to like this kind of quilt and less likely to like the very traditional sort of American quilt that's often made by older women. I'd never make an old-fashioned sort of quilt (I'm 36), and I don't use old-fashioned fabrics either. I can't stand florals, for instance. So I always find it odd when people talk about how hard it is to make quilts for men, because I don't gender any of my quilts and they'd all do just as well for men or women, boys or girls. The baby quilts are usually brighter and often feature a fun animal motif, although that said, I just made an elephant wall hanging for a pair of friends of mine which is quite similar to an elephant baby quilt I'm working on now.
