Well, if you want to compare this to the Doctor's lives, I would like to humbly point out that John Smith (Seventh Doctor) and John Smith (Tenth Doctor) are different pages. Again, I do not deny that there exists a clear in-universe link between Aphasia and Daughter of Mine.

However, I do not believe that link is sufficient to establish that Aphasia and Daughter of Mine are the same person in the same way that the First Doctor in An Unearthly Child is the same person as the First Doctor in Twice Upon a Time.

"A different me", "not quite her" are phrases which could mean many many different things in a big sci-fantasy universe like the DWU. Obviously the metaphysics are completely different, but you could have Sutekh say that Anubekh is "a different me… not quite me". Ditto for the Aztecs Doctor relative to the original First Doctor.

For a completely different technobabble explanation, you could also imagine familiar with (or some other post-Delgado Master) encountering the "Kisgart" Master from the Unbound Universe, and noting that it was "a different him" who did X misdeed, "not quite him".

And again, you'll note that in both cases, even though those statements are true and a clear link exists between the two likened individuals, we correctly hold them to be different persons, worthy of separate coverage. As we cannot know exactly how Daughter of Mine relates to Aphasia, it is the more conservative, text-based answer to keep them separate, even as we describe at length the relationship we do know about.
