That's an unusual approach but I think it would work if you use 2 separate
ducts similar in size to the inlet and outlet areas of the unit and make
them reasonably short. I am not going to address the efficiency, safety,
practicality, adviseability, or other aspects of your idea.

Thanks Don.

In doing some Google searching, I found this old post:

----------------------------------------------------------------
"Adding ducts to an AC window unit
. . . if you will get with G/E and Whirlpool and you will find out
they have a duct adaptor kits to tie on to window units on 16K, 24K ,
and 29k window units to use duct work on the units to use in
commercial applications. Also even Sears has a adapter kit for
the 24K & 29K window unit to be put on trailor houses. Now of course
my sheet metal man can make them cheaper than buying them . . . about
5 years ago I did a job with 3 G/E 29K window units and did have to
order the duct kits to install them and get the pattern for my
sheetmetal man to look at and start making our own duct adaptor
kits. . ."
----------------------------------------------------------

So, it does look like this sort of thing has been done before.
