Well...Ben Hall did it a couple years ago on his A cat.
I don't recall pitch-poling to be a problem but maybe some of the A cat guys who raced against him can tell us why he eventually dropped it in favor of a tradional mast/sail combo.
Have a big bank account and a bigger ability to keep your boat pointy side up. Jay, with current design hulls I don't think the wing would necessarily force you into a pitchpole, but the extra weight aloft of it can cause pitching moment than can certainly help go glub.
