Considering all they need to do is redo the front struts a little bit with a new mounting format, I'm shocked this hasn't been done yet. The rear could be left completely the same, and the front just needs the mounts changed, while much of the rest remains the same. I know this because we took pics of each strut (remember those threads?) and found there are very few differences that matter, other than the bottom mounting points of course.
I wish I was very wealthy, because I'd put some R&D time down with a custom coilover maker and have coilovers for the whole lineup by now and recoup the cost with variants for Explorer, Taurus, Flex, and whatever other cars are based of the platform.
