I've also wondered if a conversion kit could be manufactured for the existing WE CO2 mags that would replace the 12g and retaining nut with a small reservoir and fill valve? I'd love to end my reliance on 12g powerlets!

ProWin CNC GBB M4 Magazine CO2 high pressure test - YouTube
If you are talking about this, they are only testing the magazine at higher pressure to show that it doesn't leak. The pressure in the magazine is a fraction that of the 12g cartridge, the rest is spewed out from the nozzle while filling it. It's a very poor way of leak testing a magazine. In the end you can see very little gas is in the magazine as he vents out the gas.
