If you take a look at Jim Lee character designs over the years, you notice two things: 1. He's got a certain physical look for all his characters (and a great appreciation for the female form LOL). 2. He's not afraid to go bulky or overly elaborate on some designs, especially when it comes to armor. I wasn't terribly surprised by the bulky stuff considering they looked to be following a Jim Lee aesthetic. Doesn't mean I'm likely to use it, but I know it's something he does. As for the physical look of his characters, body sliders would most likely disrupt the look on those characters to the point that they would look out of place with all the other Jim Lee aesthetics already in place. I think sliders could come into place in some form but they'd probably be pretty limited, both to keep as true as possible to the design aesthetic and not warp the armor/clothing designs too much.
