Is it possible to define the thermal characteristics (ThermalConductivity, MassDensity and SpecificHeat) of a 3D geometry as functions that depend on the position within the geometry?

Yes, you can. Sorry, the documentation is not yet explicit.
Define a function f = myfun(region,state) and pass @myfun as the value. For examples that are not in the heat flow setting, but in the general setting, see the ways of specifying nonconstant coefficients for general coefficients such as for the f coefficient.

The only way to assure yourself of that is to make a geometry that has internal boundaries along the regions that differ. But that can be hard to arrange.
