Default upgrading a diversion charge controller

Is it possible to add a float charging/trickle charging system to a diversion charge controller? Meaning that when the diversion charge controller senses the battery reach a certain voltage and then diverts the incoming energy to dump load there will still be a float service/trickle charging still going to the battery just to maintain the battery.
Why i am asking this is because i realize that diversion charge controller doesn't give the battery a good charge like how PWM charge controllers does and the reason for this is that diversion chargers just senses when the battery as reach a preset voltage which doesn't really mean that the battery is fully charge as yet then it just sends incoming energy to dump load whereas the PWM chargers senses when the current been drawn by the battery drops to a very low current like less than 1 amp then it switches to float mode to top of the battery.

So would it be possible to add this function to a diversion charge controller making it still behave like a diversion controller but charge the battery more efficiently with the aid of a float charging service or converting the diversion charge controller that it doesn't send the incoming power to dump load until the current been drawn by the battery falls to less than 1amp which would show that the battery doesn't need anymore current?

Your diversion controller senses battery voltage to switch to the load. If you try to divert power back to the battery, the battery voltage will rise and hold the diversion controller to the diversion load longer. This would be fruitless, IMO..
