Again, it isn't about that. Once again, imagine this. It'll be me making stuff up, but you'll get the idea.

Let's say that in a 2001 a short trip short story was published we were introduced to a "Twelfth Doctor". He is noted as being tall and thin, reasonably old, and with grey hair. It's said in the story that he has a Scottish accent. Very similar to the 12th Doc created years later. The story deals with him creating the Valeyard to attempt to live past his 13th life. When questioned about it, Moffat says that he had never heard of the story and that they are not meant to be related. On TARDIS we have a huge chat about if we can combine the two characters. But of coarse we can't, they aren't meant to be the same incarnation. Even if both are exactly the same in looks, voice, character, and number, they were created years apart by separate people during times when the franchise was much different.

Here the case is even more disparaging that that would be. Here we're dealing with a character meant as an antagonist vs one meant as a protagonist. Combining them is going against the wishes of their creators and is wildly speculating.
