Even with a Hooter Shooter there is a constant anchor, the anchor cannot be taken out of the equation. The anchor point is the most important part of the equation. You can remove the peep, you can remove the sight, you cannot remove the anchor. You can align the peep with the sight housing in a Hooter Shooter, then raise the release aid and still align the peep with the sight housing but the POI changed because the anchor position changed.
