Custom Two-Player Panel for a PS3 Cabinet?

I've been looking around the 'net for a two-player control panel for a future PS3 cabinet build. I've seen some of the Blast City panels and was wondering how easy/hard they are to mod for PS3 use. Also, I have a spare PS3 Madcatz TE. I've been thinking about finding another one on the cheap, throwing them in a custom panel and putting art down over the top so it appears seamless, as one solid panel.

Any words of advice/caveats? It'd be nice to mod one of the Blast City panels but I'm not confident in my modding skeelz at this point. Any one use two TEs cleverly? Pictures are approved. ;)

Peace!
