Having read Papillon, there is one orifice available, but I'm not convinced it would make a good pocket. And no, I'm not willing to participate in that scientific experiment.Go for it! Talk to the dive op and let them know your plans. If they don't agree then move on to the next one and maybe do a private charter.
Just don't make the mistake of comparing kicks or bp/w and jacket bc while nekkid. There are only one correct answer for those in some groups. I'm pretty sure the GUE and DIR crowd wouldn't agree since you wouldn't have any visible pockets.
