FWIW, I use Pitlock Skewers on wheels with Avid BB7 disk brakes running 203mm rotors on my Big Dummy cargo bike. They slightly complicate getting everything lined up right, but its doable with a bit of finagling. Other than that, no problems so far.
If I recall correctly (haven't touched 'em since it got set up), the Big Dummy does have lawyer lips. My understanding is that the concern seems to be that the brake pad on the brake could cause a rotational force that would pull the hub out of the drop outs. I'm not entirely sure why this would be so much less likely with a standard skewer than it would with a pitlock. It does seem like some geometries of brake pad position to fork drop out mouth position would make this more or less likely - I'm guessing a front pointing dropout mouth would be more susceptable to this sort of thing than a downward facing one. Anyway, I've heard people express the opinion that the concerns re: locking skewers and disk brakes are overrated. I'm not aware of anyone having actually had a failure, but I haven't researched it heavily. YMMV. If you're really concerned about it, the custom lawyer lipesque solution is likely to be just fine. - phædrus.
