Sorry, but I remain less than impressed with your suggestion, though I too have never flown on one of the planes that you're implicitely plugging.
I, for one, have never brushed shoulders with "the cart" (my feet are a different matter), much less encroached upon the space of my fellow pax (who even on the spiffy EMB jets comprise a full 50% of the crowd) due to activity in the aisle.
May I ask where you found these stats (in your OP; the rest are well documented)?
