Perhaps that answers it, and it would be best undertaken if (and when) we get more familiar with the underwater landmarks.
Given that the currents are so mild in Bonaire, it's really not necessary. Maybe after you get bored diving the 50 or so regular sites too many times, but that will be a while.
The prominent drift dive in Bonaire is from La Dania's Leap AFAIK, because at that site you can't get back out where you jumped in. Or maybe I'm thinking of Rappel. Who knows? I obviously haven't done either
Whatever dive it is, you can hire a guide at a reasonable cost to successfully take you on the drift.
Otherwise, most of my dives in Bonaire are half drift dive in that I swim against the current in one direction than let the current drift me back to my starting point when we're at half a tank. I'll make the return shallower in order to see different stuff and ensure enough air to get back. Practice memorizing your starting place since not all sites have buoys and sometimes those can be hard to spot depending on your depth.
Oh, and I'm not worried about what someone might do to her. It's the damage she can do when left alone. For, you see, she has powers. Incredible powers.
Every diver should carry duct tape. A few wraps around the ankles, a few wraps around the wrists behind her back, and a strip across the mouth and she'll be trussed up and waiting for you when you return. (Note: I don't suggest this as a normal agency sanctioned buddy activity. Please be aware that duct taping the mouth has certain risks including, but not limited to, suffocation and death. Even if she's your wife, I recommend you at least have her sign a duct tape waiver.)
I agree with Mossman that drift diving in the southern part of the island is going to be a whole lot easier than on the north side. In the middle section, the diving is great also, but since there are numerous hotels and dive ops from Capt Don's Habitat south to Leh Dehman and you might have a problem finding a good spot to get out of the water. Last year our group drifted from the Habitat south to the Sand Dollar and got out of the water at the Sand Dollar planning on having lunch there. Unfortunately, the dive op owner at the Sand Dollar was a real *%$#*^@ and pitched a fit that we used his stairs to exit the water. He basically told us that since we were not guests at the hotel or were using his dive op then we could not use his facilities. He would not even let us park our gear while we ate. So we left, and will not set foot on their property in the future. Their loss!
Please don't take Andre's attitude out on the "property", whether it's the Sand Dollar Condos, a very popular place to stay, or Den Laman Condos, my favorite place to stay. The owner of the dock happens to be the owner of the dive shop between the two condo facilities, Bonaire Dive & Adventure. Besides Andre (who's always been nice to me BTW when I've stayed at Den Laman and bought the BDA nitrox package, but I've heard rumors that's he's not always Mr. Friendly), BDA is unpopular for their long briefings (zzzzzzzzzz), limited gear room hours (soon to be fixed I hear), and I didn't care for their boat dives because you have to assemble your gear after you arrive at the dive site with the boat bouncing in all directions. Their air and nitrox taste just fine and tank swapping is easy with their facility in the parking lot, plus I've always been able to use the dock as a paying customer, but I can see why those unaware of the dock restriction might be put off.
That said, it's simple to walk out on the little sandy area next to the dock, not any different than the southern shore diving. Also, BDA isn't the only facility that restricts use of their dock as I believe either Buddy or Capt. Don's do the same to some extent (they might just require a signed waiver or prior permission, I forget).
