I was sort of thinking of flushing out the whole system and converting it back to AutoFrost, or even R12. Though I know that the HC refrigerants are NOT good in a leaky system, because the individual component gasses do not bleed off at the same rate, so if you have leaks, you end up with a sub-optimal blend of gasses.
Guess if the R134a has eaten the O-rings I need to replace them in any case....
