I'll take a shot at this...................
It would wear down the motor but not anytime soon. It will add noise to your powerhead and the impeller churns up the bubbles.
I think I see a problem with your theory. Yeast the reiceve a constant supply of O2 would deffinitely live longer. The problem is CO2 loss. IF the CO2 bottle isn't sealed, you will not be recieving 100% co2 but more O2 than CO2. Adding O2 into your tank will in fact reduce your CO2 uptake. A setup for your system to work would cost more than a typical DIY unit should. Probably be cheaper to buy a 5lb CO2 bottle and use a DIY reactor (less than $140.00). And the tank would deffinitely last longer. I like the idea though.
