I've got a spare set of the charcoal baskets, and have used a single one in the 18.5" and in the Smokey Joe. In those cases I managed to fit a drip pan by manhandling a smaller square foil pan, loaf pan, or pie pan. It's a tight squeeze, but works well enough, especially as an option for camping with the Smokey Joe. I think with some heavy-duty foil you could probably do even better.
Both baskets definitely don't have enough space between them to count as a 3-zone fire, but that setup can also be useful for bringing the coals closer to the grill to put a serious-hot sear on a steak.
If I were trying to smoke something on one of these smaller grills, I'd use the snake method with a pie pan in the middle to hold water, and I'd probably do a practice burn or two to see if I could hold temp before putting anything expensive on a 18.5" to smoke.
