Go for the flanges. Unstiffened, any bends of the plates large enough to cause issues would have to go across the entire plate. You probably won't have any issues with distortions which only exist in the center of the plate, which are the only kind which will be allowed to form with proper flanges in place. If you're still concerned, ease off on the lightening a little bit, it's probably overkill for 1/8" plate anyways.

My team has done similar gearboxes in sheet metal with flange reinforcement in .090" thick metal with no issue, and I've heard of lighter.
