Could be completely wrong but I'm thinking more like SZ Territory bonnet,
headlights and then corporate Fusion /Taurus look below that..

Thinking parts sharing plus letting the plastic nose do the differentiation work..

Maybe a rework of Territory rear tail lights and new boot lid for a different look at the back..
maybe different crease lines in door skins..

The above changes would be fairly straight forward but give a huge change in appearance...
