I understand that you want the exact location where the line of sight to the landing spot pierces through the bubble stay fixed.
This requires a) a constant angle approach AND b) unchanged attitude, as failing to achive any of the two will cause that point on the bubble to move.
But while satisfying both a) and b), the air speed can be either constant or progressively decreasing (I fvor the latter).

So where's that "walking speed over my toes" thing come in here?

I once had a FI demonstrate an approach where he setup ship at app. 60 kn @300ft and apparently didn't move any of the controls while we went down the line of sight like a cable car, constantly loosing speed.
He simply waited until we fell through ETL, pulled a tad pitch and we hovered at 3 ft. I was very impressed
Maybe he did the walking toes thing, I don't know.
