I feel like it would be easy to repair by evening out the down and the carefully having the open part of the baffles sewed. I even considered just stictching a small spot in the center of the open part to restrict free movement of the down.

I know...you shouldn't have to do this. I have to believe the open baffle design isn't unique to EE quilts, maybe the lesser amounts of down in the 30 and 40F quilts just allows too much room for the down to move about.
