At this point, I'm actually strongly considering either A) teaching myself how to make custom pads or B) finding someone that can make them for me. In reality, both situations don't have much likelihood of happening, but we'll see (if there is anyone interested, I might be able to invest...).
The jergpad-style modded alpha pads bring a lot to the table, namely in comfort and openness of the sound. The best way I can describe it is that it sounds much more like a pair of decent speakers placed in front of you rather than two large drivers strapped to the side of your head. The sound is overall lighter, but not lighter than, say, the HD598 (from my memory). I know I've said all this before, but I want to emphasize that there's enough there to the sound that I think pursuing the custom pad route could be extremely rewarding. I am thinking, in theory, you could make pads the size of the alpha pads work really well, but it would probably be easiest to start somewhere in between the stock pad and alpha pads. This might also present an opportunity for custom pad mounting solutions as well, though that's likely not going to see as many tangible returns, and you could easily make a custom pad work well with the stock mounting rings.
Edit: Actually, one of the more practical reasons for having pads not quite as thick of the alpha pads is due to fit. I have to extend the headband as far as I can with the modded alpha pads to make the headphone fit right, so this could be problematic for those with even larger heads than I. I'm left no room to add padding to the headband in this scenario, unfortunately, though the alpha pads as-is do wonders for comfort and weight distribution. The additional comfort alone makes it hard to go back to the stock pads in any form.
