Wow that is very simple! And if you happen to work at a gas station or restaurant with a pop machine (or know someone) you could totally fill a corny that way.
BigK if you have an extra empty corny around the house you can pressurize it to the higher pressure you want. Then connect the inlet on that to the inlet on the keg with pop.
It is not a perfect science. Obviously as the soda adsorbs the co2 and as you dispense it the pressure drops. But if you are just trying to up the carbonation a little it should work. Plus you can always give it an extra hit of co2.
