Yep, I've mentioned before that I have a theory that the rewriting you mention is the natural process of regeneration, but that Ten went out of his way to subvert it by trying to make it easier for Rose. He tried to become more human, and it led to many of his problems.
That was very much on my mind, actually, and originally I had a section on the Nine/Ten regeneration in here, but I cut it out in the end because it went off track. But yes, I agree very much. After all, Rusty himself said that she imprinted on him - which is why I don't mind the focus on her that the show had. She was Ten's focus after all.

It would also explain why FoB created such an explosion and strong reaction in his personality.
*nods a lot* It all makes sense.

Good meta.
Thank you. :)
