I am very excited today. In my best George Takei voice: "Oh, my!"
I tried out the wick configuration pictured above in andrebandre's post. I used the cartodriver to remove one Diver, and inserted the other with the new coil&wick last night. Specifically, 32g Kanthal A-1 and nickel NR @ 1.3 ohms, 1.5mm Ekowool. It had about 1.5 inches of Ekowool on each side, but I only trimmed down one side of it. I would have kept both, but it would get too crowded in the Diver stem, and it won't screw on with that much wick sticking out the sides of the base. Once I had trimmed one of the two sides of the wick, I took a very long, thin awl, poked the needle end into the top opening of the ceramic, and wrapped the remaining long wick end around the needle of the awl. I then slid the Diver top down the awl, screwed the top on the base, and removed the awl. I trimmed a bit off the end of the wick that had frayed, and used the awl to gently adjust the wick, which had coiled around the inner surface of the Diver top.
I did this last night, inserted into the Scuba 
tank, topped the tank off, vaped a bit, and let it sit overnight. I would normally have woken to a few drops of leaked 
juice between the Scuba Diver and the top of the Lux. This morning, it was bone dry. The vape is perfect - zero gurgling, and not a hint of 
juice coming out the bottom of the Scuba Diver, even though the tank is full. This is from the first drag onward. With the usual wick setup, the first few drags always had a bit of gurgling. A full tank always leaked a few drops out the bottom.
I will swap out the same configuration a few more times this week, to make sure this wasn't a one-off lucky perfect setup. If this works, I strongly recommend everybody try out this setup. I'll try to take a few pictures when I do my next setup, to clarify things for folks who want to give this a try.
