Planning to tuft test the basic teardrop shapes in the next few days, and still haven't totally decided if we'll use a tailgate or clamshell/hatchback style system.

Yes, I understand that, and I've considered aftermarket rear window spoilers before but didn't find any that were proven to be beneficial at the time. The car is fairly slippery stock and I didn't want to introduce things discussed in this thread. I'm happy enough with the car being stock for now and am focusing on the general aerodynamics of the trailer since the tow vehicle could (and likely will) change in the future but I'll always use the trailer at times.
