No I don't think an Escort ZX2 grille would look very good grafted on to a Crossfire, not that it has any real grille above the bumper.
I have both cars and keep their respective parts separate at all times.
You don't see many Crossfires on the road though when I see one with any grille (even more rare) like this I just have to ask "Why?".
When I was looking to by my Crossfire there was a halfway decent 05 Limited coupe at a dealership, it had a grille like this, I didn't even bother to consider looking at that car any further.
