which one could be dangerous during approach?
All I can say regarding the second scenario is: when setting QFE 1020, the altimeter reading will be 0 at the airport to which the setting is referenced. If you then wind down the setting to 1002 QNH, you will get the AMSL altitude of that airport, which will be significantly below 0. Perhaps it's close to Death Valley! 😜
