As one who has added cladistic information to panbiogeography I will be very curious to know how you come to that conclusion? Also, Heads provides extensive analyses using molecular phylogenies to generate panbiogeographic reconstructions. Again, how does that make his work 'panbiogeography light'?

Not correct. Phylogenetics was in existence in his time, and even cladistic applications were around early in the 20th century, including one author who also supported the vicariance model.\
The bottom line is that phylogenetics (of biological characters) cannot provide spatial information.
