Dylan,
As far as modding headphone earcups goes, earcups make up a big part of how the headphones sound, and all the materials you listed are probably uncomfortably more heavy. I wouldn't try, personally. If you don't like the look of plastic though, why not try covering it with some sort of veneer? Might even look cool with the combination of the chrome/aluminum rim and leather that looks like it was stitched on.

Since the K272 HD has velour pads as well I can very much recommend them. I was almost picking them up, that much I enjoyed listening to them for the shy asking price. I didn't find the bass to be THAT lacking as the graph suggests and the spike around 9kHz wasn't introducing any sibilance from my experience, a pleasent smooth sounding highrange with decent airiness to them despite a closed headphone but those beautiful warm mids were the best of it obviously. Soundstage was also large.
Those refinements sound like exactly what I would enjoy. The problem (& reason I asked about size) is I'm so happy with my Q701 that I really only need a sealed can for traveling & portable use. I dunno,
maybe I could get away with something that large on an airplane, probably would be ok at a desk job, but right now I have no desk job or airplane trips and I just can't justify another headphone purchase. Someday though, I will have to either try these K272 HDs or a Sennheiser 600HD (as stupid as the trend is to call headphones HD, like some sort of LCD TV). Wish I could find my Crossfade LPs, they weren't going to win any medals for detail and realism, but they were fun & I'd just gotten them broken in & comfortable.
