Ventilation Setup

I am finally getting all the pieces in place for my 5' x 3' x 8' closet grow. I will have a 600w hps and a totally sealed room. The issue i am running in to is I dont really want to cut 4 6" holes in the ceiling of my closet.. I have a 500cfm fan for air exchange that will be attached to a cf, and a 125cfm can-fan to cool the light. Here is a quick drawing of my plans as they stand:



Everything here looks great, except for the 4 holes I need to cut in my ceiling. Im thinking it may be worthwhile to combine the systems, like so:



The obvious problem with this setup is the warm air being used to cool the light, although Im not sure how much of an issue this will be. The temps in my area rarely get out of the 70s, and I will be pulling (relatively) cool air from the attic. In any case, I hope to keep everything at a slightly negative pressure to keep the smell under control..
