It could work on a part61 track, if you are well prepared for the written test on arrival. That means the use of something like the multimedia-home-study-course from jeppesen or others (i.e.
www.fliegen-usa.de/shop_cpl.htm).
I did it in 2004 in that way in Texas, and finished after 16 days with checkrides for single- and multiengine . A supporting factor was probably, that I obtained a German ICAO-ME-rating a few years ago.
Good luck and happy landings!
