I agree that the green coolants are low risk in a new system, or a system already running it, but dexcool and ethylene glycol do not mix well and ensuring you flush all of the dexcool is a challenge.
That being said, if I knew that was the answer, I would absolutely go for it. What I dont want to do is throw another radiator at this thing, swap the coolant, and just hope for the best. Id really like to find a definitive cause...or at least someone who can tell me one way or another if the .2ish volts across the coolant are what is causing the radiator to deteriorate so fast.
