If you know the volume of air you'll be moving then recalculate the flow velocity at the interior area of the pillars.An ASHRAE Manual would help you calculate the static pressure necessary to move that volume of air against that much wall friction.
And you'd want to know how to deliver the air to the roof at the same velocity of the flow already there,so as not to create a drag-inducing jet.
