Good luck! but don't hold your breath.
There have been a number of attempts to put some discretion into the hands of competent people over the years. None of them lasted.
There was a time when exceptions could be granted by the Minister, but he got jack of it - "I wouldn't normally bother you Sir, but your daughter is on the aircraft" is one (genuine ) line that I recall.
"Green" considerations would extend beyond curfew issues to the efficient use of airspace - imagine what that might lead to.
Count me among the less than hopeful.
