Clever priming sugar required

That's going to be interesting read thanks.

My current plan is very experimental to get gas bottle free. So beers are primed over pressure to start with. Then brought down gently and the excess gas used for dispensing the drinking keg.

No need to over prime if you're producing gas with sugar, just regulate the pressure going to the serving keg.

You can over prime without over carbonating, by spunding the gas into your reserve tanks .
