Just an idea here, but I think some styles could really be able to overlap others of same kind? Especialy the hood head styles that could be put over small helmets like the skull, slimlines and such, looking a bit like this: Something that can also work with styles like Main Man overlapping other chest styles and the Kryptonian Medico and Magnetic Paladin overlaping with other capes.
You know what would be really cool about this? It would let us put the Santa beard on the new No-Beards-Allowed hairstyles, and still wear a pair of glasses.
I could imagine a bunch of new awesome styles if that was allowed for.. and monstrously bugged out creations that Trigon himself would be proud to call his own.. So I'd totally be fine with it.
