As long as that ADS is an optional module that would be fine. The idea of having the pinpoint coordinates, knowing where they are and then having to find them again in the FSS would destroy it for me.The best analogy I can think of is that some people like jigsaws and other people like colouring books.
The FSS is for the jigsaw people, building up a picture of the system piece by piece.
The ADS was more for the colouring book people - starting with an outline and filling in the detail.
Yes, the old ADS provided too much detail too start with - most people admit that, but if you don't like jigsaws, it was still better than the FSS.
My ideal would be a toned down ADS that provides a less detailed overview.
Selectable targets so that I can choose to fly to targets before scanning.
And the option to use the FSS while I'm on my way.
Best of both worlds, a choice of methods to mix and match as you see fit.
