The only reason you would want to significantly increase the lighting on tall buildings etc etc
That is
not my reason. Nor do I advocate any of the changes you mention. I have already given my reason so won't repeat it.
I have flown the heli routes many times but I fly for pleasure not work and don't fly daily so I've always been a self-imposed strictly
very 'fair weather only' pilot when flying a helicopter and therefore not in a position to answer your question in any useful way.
The professional helicopter pilot community in the UK is relatively small and many people know, or have a shrewd idea, of the identities behind usernames so I don't think you can reasonably expect your enquiry to be fruitful.
You clearly think this pilot, who was very experienced, made some poor judgments that day. You could always try asking other pilots if they've ever done so?
I doubt if there many pilots, rotary or aeroplane, who have not. (Just like those of us in other professions.)
