me,what i would do is,assuming those are 6 inch and those two ducts go straight outside is this..
use the duct above the door for hood ventilation,stick a carbon filter and 6 inch fan at the window end of the room and blow through your hood and out.one straight line...
then i would use one of the window ducts as an intake with a 6 inch fan on a thermostat and run a length of flex duct up high to the other end of the room.keep it high so the cold air has a chance to mix with the hottest air in the room.
then put another carbon filter and 6 inch fan down low at the window end so you have your fresh air coming in one side of the room and being drawn out high and low at the other end,with at least two oscillating fans pointed up,again,one high,one low...
then even when its cold out with two exhaust fans going you should still get plenty of passive air flow in..
