Howdy, Swareiam.
I don't think we can go that small on graphic elements. The patches end are 3" in diameter, and resolution to the stitching isn't all that high. The planes smaller than the bombers, the explosions, and the USAAF symbol would end up too small to render well.
If you look at Operation Husky, those two aircraft are pushing the limit on size of an aircraft shape. I would go bigger than that. Also, if you look at the symbols on the wings of the planes in Stalin's Fourth and Operation Downfall, that's how things get at small sizes.
