Sciolistes,
I take it you fly the 737.
Your comments about having to dive bomb the ILS, or needing thrust to maintain the G/S are just not accurate in many aircraft.
The 767 for example will happy fly a 3 degree ILS with Flap 5 at idle thrust. (It can be a slippery little bugger!)
So, if you want to be idle thrust at 800ft it would be easy. join the ILS at Flaps 5 speed (say 180 kts) and fly 180 down the ILS at flap 5... you need idle thrust to do this (and you might still start accelerating). Gear Down, then Flaps 20 at about 1200ft and then 30 all while at idle. When the flaps hit 30, and you're at flap 30 speed, power up.
This is essentially what we do in my outfit, EXCEPT we arne't lunatics configuring that low
Take the gear and flap at 2000ft, so we are stable with power up at 1500ft.
