(Most) planes use the skin as a load bearing structure to reduce weight. Punching holes in it is therefore mostly avoided, and those holes that are required (windows, door) tend to be designed to minimize stress points. Your proposal would require a massive increase in weight (or reduction in strength/rigidity) that would most likely offset any benefit from improved loading times. Aviation is all about trade offs. Even when I was doing systems software any benefits from software upgrades were compared to weight/power/cooling/operating costs religiously.
