unless your DP is very unusual, he shouldn't object to doing the logging and translating with you (and not the edit). he might object to logging and translating in general, but he'll certainly understand that you need to edit this locally back in NYC.
one thing to keep in mind is that logging and translating almost 20 hours of footage (or even 10 hours) will take a LONG, LONG time. for every 1 hour of footage, i would estimate at least 4 hours to turn that footage into a transcribed, translated, timecoded document – and i believe that is a very conservative estimate.
