Your suggestions aren't newand have certain applications world wide.
The FAA years ago 'explored ' the 2 glideslope concept.Initially a 6degree to Intercept the 3degree about 1000/1500'agl..the application of thrust at the intercept point negated the quiet credit up to that time......The L1011 would be able to comply due to it's unique Direct lift flight controls.
In Canada certain runways suggest/request no reverse thrust -unless required,and in the night operations.
The industry might argue with the requirement for Toga Take offs every time,rolling takeoff's aren't utilized enough as ATC put you in position ,waiting the runway to be cleared.....
Banking after takeoff could be improved upon,Chicago appreciate it with an immediate turn.....
Maybe it's time for an Industry review of your suggestions
