I believe Tyrion is truly his father's son. His hair is gold, suggested to be a recessive trait in noble bloodlines. I am not sure whether Targaryen is the same seeing as Robert is descended from Rhaella in the books and has Baratheon features. However, the fact that the hair color is a pure blond suggests that he is pure Lannister or the colors would mix.

I mean, later physical evidence can contradict this but it is definitely an obstacle. Another one is Tywin himself. The time window for Aerys with Joanna is when Tywin had yet to sire Jaime & Cersei. The two-year gap between their births is the same that Jaime imposes on Jeyne so that there is no rumored Wolf Cub in the Riverlands.

Dragons have gone unridden before, and Tyrion is not known to have the "taint" - the Targaryen emotional propensity to rage. He is clever, cunning, his father writ small.

There's another problem...one person in Westeros has the requisite knowledge of R+L=J. However, all potentially involved in A+J=T are dead.

That is not to say that this goes anywhere towards A+J=, though its hard to prove. The complete lack of Aegon in the show suggests that Tyrion may be the third dragonhead.

What's the word on survivors in either the show or books? I think those characters are what he initially envisioned, seeing as the likes of the other Lannisters, Rickon and others are expendable. However, a specific fact of that kind would be extremely rare.
