8 Frame mediums throughout
I do it, but a little bit differently. I move two frames with eggs into the center of that bottom box of honey. This pins the brood down low in the stack of boxes. The two I remove from the bottom honey box to do this, I move to the center of the top box. This gives two empty frames to move to the outside of the brood in the middle box, for expansion sideways. This will keep the broodnest low, and they'll move the honey from that bottom box up to the top box so they can fill the bottom box with brood.
