I guess if you line the bottom of the shelf with sheet metal, I don't
see why not.

You know, now that I did another search, thats what some people do,
they just simply run the duct through the floor, and the open cavity
at the bottom of the cabinet becomes the plenum, no other ductwork,
just install a grill at the kick plate.
My only concern doing this is that if you use the same ductwork for
heat/AC, will it cause damage to the cabinet from hot and cold air
blowing on it, especially in the summer. Condensation might form from
the a/c.
