Not sure what you mean by Satellite overlay screen, but ...

IOW, you could overlay a real satellite image of the terrain around you.
That way at night with an engine out you could bring up the display of the
satellite image below and around you and see that the black area out the
window is a farmer's field and not a bed of granite or unforgiving trees.

I'd definitely like to see with regard to engine out operations is
implementation of the same "cone of safety" feature the Chelton screens

If you mean it shows a cone of the ship's best glide range, then YES I will
add that also to my wish list!!
