Haha I was thinking the same. It would taste gross and be the same amount of caffeine if not less than the original drink. Gatorade and caffeine is a good mix though since caffeine dehydrates you.

That's exactly what I've thought as well. It seems that many people had the intuitive thought that this would add the concentration of caffeine of each ingredient, but in the end, that's just an average and not much worse than each of them.
