Leveling slope in slab

Leveling slope in slab
There is a portion of the slab that dips about 2.5-3”
We have some Sakrete mix that I was going to use as a base to bring up the area to about 1.5” or so and then get some Rapid Set leveler to built up the rest of the area and feather the patch.
I planned to clean the area, prime with concrete adhesive before.
Attached is a pic of the area. It comes out from the corner where there is a back wall that is sheet rocked. Do I need to cut out 3” of the drywall? I planned on just pouring up to it - we don’t care if the Sheetrock is damaged at all.
The area is about 3-4’ wide and comes out from that wall about 5’

1. Do I need to cut back the drywall or can I just pour up to it?
2. Is the approach I described viable - making a first layer with an aggregate mix and them using leveler to get up to the height I want.

Just be aware that concrete does not bond well with cured concrete so there is a really good chance that it will eventually pop off.
If it's outside and your in freeze area it will pop off even sooner!

What if I use a bonding primer?
There would be a tooling mill being placed in that area. The patch doesn't need to last forever.
And how long should I wait to pour the leveler over the initial aggregate patch?

If I were you I would not worry about pouring up against the drywall, but if you wanted to you could staple some 1/4" Foam sill sealer to the drywall to separate the two. Just snap a level chalk line on the wall and staple the sill sealer along that line and cut the bottom edge at the floor.
And I would probably just use 2 coats of rapid set leveller. Bonding primer first... build up half of it with your first application... wait 24 hrs, then bonding primer and a 2nd coat of rapid set leveller, trowelled out to an 1/8" edge.
