First one note, AC = Alternating Current, as in electrical; A/C = Air
Conditioning. Using this convention will get better responses.
My recommendation would be to simply cut the existing duct back 12"-18"
and relocate the outlet using the existing termination components. There
should be no reason to cut and install flex if the vent is in the middle
of the room since you should be able to move it back in whichever
direction the duct is running and still be in a reasonable location.
As for the flex duct, the inner surface is more slippery than the sheet
metal, so they really don't collect that much more. Flex duct is the
norm in most everything commercial, and if the dust and dirt was a
significant problem they'd probably use something else.
