I belive there is a concrete lentil above the window and my rough measurements indicate it will be high enough to allow for the door. Doing as you suggest might be difficult because the window is near a corner. While I'm sure it's possible to do, it might be beyond my capabilities. Is there a way to fill the voids vs. cutting the block out and replacing it with the closed end of a half block?

B) Fasten directly into the 1.25" to 1.5" edge/face of the block with shorter anchors.
When you say the jambs don't have to be flush, do you mean the PT rough-in (I apologize if I'm using incorrect terms) doesn't need to be flush against solid concrete? In other words, it would be okay if every-other block were hollow behind the PT?
