That’s good to hear, but you know I don’t have time to reread the whole book right now. 
I don’t see how you could have erased the problem so easily, since in your previous workshop version you had biologically and philosophically indistinguishable humans outside the garden.
I am not saying that one can’t reconcile a genealogical model with some explanation such as, all extant humans (now and at the time of Torah or at least Jesus) are/were in the image of God if “image of God” entails merely a vice regency and covenantal relationship with God and if such was established or instantiated with a de novo (or even representative, selected and translocated) pair.
