If you are going to work upper body and stress the whole organism concept you need only such things as bench press, dips, and pull-ups as these are multi joint movements although maybe the dips are not. You are kidding yourself if you think there is crossover from training in terms of strength and power from upper body to lower body. I've seen enough tweety birds walking around the gym to know while their arms and shoulder carriage could handle a deadlift or clean weight their legs would never produce the force necessary to accomplish a succesful lift. That said, there is evidence that supports neuromuscular facilitation and recruitment in extremeties that are unused because of injuries while training the other extremity.
On a personal note, I continue to bench press well over 200 pounds without hardly ever doing bench presses and when I do bench press exercises I only use dumbbells except in cases of testing max strength and max muscular endurance. Most of this ability comes from the amount of lifts I do with my legs and the heavy weights that have to be stabilized by muscles of the upper body from doing heavy and/or powerful lower body lifts. Just the other day some of the HS XC runners challenged me to do one seated military press of 115lbs, I did 10 of them.
