Freestyle line where geometry overlaps?

Is there a way of getting geometry intersections rendered with a freestyle line?
I know that I could use boolean to generate a real geometry edge, but often this is not an option in practice.
Also otherwise useful tricks like joining together and solidifying don’t seem to make a difference here…
Appears to me that “Real Face Edge = Eligible for Freestyle Line”, but not just face intersections. Right? (Hope to be wrong here)

Just wondering whether I haven’t found the right Freestyle setting or whether this is not possible in general (yet?).
