Seems like it would be much more beneficial to actually start testing inter-continental genera (Elaphe, Coluber, Agkistrodon, Boa, etc.) to see if they really are related enough to be in the same genus (considering how long some continents have been separated, I really doubt it).
Utiger, Urs, Notker Helfenberger, Beat Schätti, Catherine Schmidt, Markus Ruf and Vincent Ziswiler. 2002. Molecular systematics and phylogeny of Old World and New World ratsnakes, Elaphe Auct., and related genera (Reptilia, Squamata, Colubridae). Russian Journal of Herpetology. 9(2):105-124.

i don't get this journal, i don't know what the author's discovered and how it was interpreted, but if you are interested in the topic you may want to email the author and ask for a reprint.
