Rubbish. You won't answer because it'll prove your method doesn't work well. The answer is simple, so simple even a newbie can understand without all that scientific energy stuff.
You get fast, you pull the power back until you get on speed, then put the power up. You get high on slope, you put the nose down to get back on slope.
If the speed changes (if only a smallish pitch correction, the speed probably won't change enough to worry about) you fix it with the throttles, just like the autopilot/autothrottles do it. Handfly an ILS and watch the throttles work.
Answer? Yes/Yes.
Simple!
You may have a few or many seconds to sit on the approach (off slope and/or off speed) waiting for the secondary effects of controls to fly your aeroplane but I don't. Pitch for glideslope and throttles for speed. Simple!
