Absolutely but you are once again getting away from your original post that the flying public will give a rats a** how many hours the boobs up front have.
If you could run an airline based solely on the fact that you'd have much higher prices based on the fact that your crew was advertised to have higher than the average flight hours then you'd leave the rest of the airlines in the dust. Speaking of dust you might want to see if you can get your hands on some fairy dust to help bring this idea to fruition.
