Volenti would be so proud of you
If i remember correctly, Volenti was the handle of an Aussie guy, and he became a legend overnight when he presented his contraption on Pro-Cooling back in 2002 or 2003.
Pro-cooling is a bit of a mausoleum now, but back then is where the smartest guys of our generation hung out. I think 3/4 of them were engineers. And if one of them would have been able to focus his mind on ONE thing (like world domination) for like longer as 10 minutes, the world would be a different place today
Anyway, volenti got quite a following on several board across the world... The volenti inspired Project Rainfall
was one of the most interesting implementations in the recent years. And one of the most good looking will be a wooden
one (if it ever gets finished)
(Its difficult to find pix that are 10 years old)
But one of the most "elegant" implementations -and not that long ago- was/is Sleeperman's PE tank : http://www.overclock.net/t/1315440/volenti-cooler-using-pe-tank/0_100
Might be worth trying something like it.. you've got two holes in the lid of the coleman already.. use one for air intake, and exhaust to the outside through the "stovepipe". Can even combine: have an upright part in the exhaust, and have a few stretched "towels" in the Coleman
I think this is about as deep as you can go ... unless you can get the RH% down.
Maybe you can run the intake air throuhg a dehumidifier before it goes into the your setup... although you've gotta ask at which point you're using more energy than as you would by making a cabinet around the A/C
Gotta run the numbers again ... assuming level air intake temp (from A/C room) , if you could reduce RH% to 10% , you ought to be able to shave another 4 °C off ( 6° if you could reduce to 1%RH)
But i think this is about as low as you can go... 14-15-16°C with no load... now its about size i guess... the more surface, the more capacity.
Need to test if this thing can keep a heatload under control. The easiest is to sink something like a 300/600 watts water heating element in the coleman
