Yeah, that was the direction I was thinking...even if the Hurt Doctor's sonic ends up being an entirely different design, I just think that the alt 8th would definitely work with a more sinister color scheme...perhaps a gunmetal body, with dark mahogany grips and, as I said, a bright red LED...
I really don't think you could have done much better with the push switch housing--as I used one of the original small switches from the CO sonic, there was a lot of wiggle room, so I had to use something to anchor it in place (hot glue, although epoxy I think would be better, as I noted above...), but had I went with a normal-sized switch it would have been perfect, so I'm not complaining. Really, the only problem I had with any of the WSF parts fitting was, strangely enough, the trigger ring...I just couldn't get that little bugger to sit straight, but finally I got it close enough, and I figure if it's a little off, this is supposed to be an old, beat-up screwdriver so it can't help but add to the charm. And I'm with you--I can't wait to see more finished kits!!
