Might it be pracitcal to hinge the door on the other side? Could it open more widely that way? Usually they are set up to open with the hinge towards the front, I suspect because that way if it's somehow open or unlatched when driving the air flow will tend to force it closed. However, I would have no scruples about having mine open the other way around if it made more sense otherwise.
A chain or similar screen door-style check is a good idea. A bit of wire rope (often called aircraft cable) would work nicely too and probably rattle less.
