I think you are onto something there. I have a four-car with 4 feet between the two. I moved my bench into that middle area and took a little of each side of the garages, it left a ton of room for my Excursion and the 4runner looks lonely on its side. I have cabinets on both outside walls of the garage that impacts the area to park cars. So I think if you moved everything to the space between the two sides you'd have plenty of room and it would be better access to everything in the garage. The big key, like mentioned above is getting 8' or taller doors, but for the most part that has to be done when the place is built. I'd try your idea.
