The last few pages are delving very deep into cringe territory. At least it's entertaining.

I was against it at first, but it's starting to look like a good idea after some thought.

This will completely destroy the crafting market because urgent demand is eliminated. Raiders will be able to craft their own gear.
In my opinion, crafted gear is unhealthy and awful for many reasons, but that's a different discussion.

The primary advantage I see is that it would be healthy for world first prog. If teams are able to prepare for a week, then they all start at the same point without the need (advantage) of outside help in terms of gear and consumables.

Not so sure about having one week to study normal raids - it will eliminate some of the surprises.
On one hand, it's an interesting exercise in speculation. On the other, previous experience with this game's raids allows you to predict how some of the mechanics will change.

What about delaying both Normal and Savage?
