They have built several, but the rest are not so directly integrated with the earthbag wall.

Bricks, I'm not sure.
I compare slip form masonry to a poured concrete wall.
Every stone that you use displaces some of the concrete.
The stone finish excuses imperfections.
Maybe cob could be substituted for the concrete.

It's more resource intensive than dry stacked walls or even conventional mortared stone walls but also requires much less skill.
Sometimes a foam core is cast into the middle of such a wall, creating a system that has a weather resistant exterior , high mass interior and a continuous insulative air barrier.
