I reckon it'd help, but as Jim Akiba points out, the compression of
the air flow over the top, down the sides, and under the bottom are
rather small potatoes compared to the turbulence-induced vacuum caused
by all that air trying desperately to re-fill 3/4 of a cubic meter of
space across a 1.5x1.5 meter plane every 1/100th second. That
near-flat back end is a killer.
