If the 3.2 is cheaper (I doubt that) or offers better fuel economy I can see it being the standard engine in many vehicles (or at least trim levels of some vehicles) where the 3.6 is now included.
If Chrysler and Dodge both keep minivans (we've heard rumors that one then the other is changing) it would make sense for a Dodge version with the 3.2 as the base engine while Chrysler would keep the 3.6.
