Some years ago, Jack Belrose, VE2CV suggested that one of the better ways to approximate ground characteristics at a given frequency would be to erect a precisely measured low dipole just high enough above ground to accommodate the limitations of your modeling software, and then tweak the ground characteristics in the model till the resonant frequency of the real dipole and that of its model match. This sounds like an approach that would largely overcome both the inhomogeneity problem and the frequency problem. Critique?
