When filling with coolant it should take 10 minutes max, the car won't have overheated by then.
Airlocks you say, how are you any more likely to get airlocks in a system with a running waterpump, than in a system without one? Water is more dense than air and therefore with some encouragement the air will rise to ths top, whether the engines running or not, which is when you open the bleed point which is at the highest point in the system.
The running would probably help as hot air rises.
You cant say that hot air rises helps. Hot air leaving is not going to draw water in! Also isnt the temperature gauge on the dash the water temp? Itll never display hot if there is no water in the system so it probably is overheating but it cant give you a reading. Anyway... Ive working with marine engines and running them without water is a big no no.
