Good idea or over complicating a simple water change
I have been reading how important it is to get the correct temperature for water going back in to the tank after a water change and my mind being as it is thought "what if".

Well here it is I'll do my best to explain. I have a external canister filter if I could get a two way valve to sit on the intake of pipe of my filter, one side going into the tank and the second going into a sump containing my declorinated water, also in the sump a heater to bring the water up to temp. On a normal day the valve would be set to filter the tank. After siphoning the water out I could then switch to the second position which would take water from my sump/bucket through the filter back into the tank, thus(never thought I'd put that in a sentence) ensuring there is no debris in it and also passing it through the biological media adding beneficial bacteria to the water. As well as that it also returns water to the tank in a controlled manor.

Does anybody do this? If it's been tried what were benefits and down falls? Or as I say just over complicating things?

Complicating things
I see no real advantage.
I add water from my well on the suction side of the pump in my central filter system, but for no particular reason other than it was a covenant place to supply the feed water.

I just use my hand to guesstimate tap water temp vs tank water temp, adjust at the tap and then flip the valve on the Python to start refilling once it's close. A few degrees is not going to hurt the fish. In fact, doing a water changr with slightly cooler water can trigger spawning action in many fish as it imitates a cool tropical rain.
