I feel like that would needlessly complicate the story. Aerys was saying 'Burn them all' because he had a nasty case of Targaryen pyromania, his enemies were at his gates, because he was spiteful and insane, because he had rigged the city to explode, and because he thought burning everything down would turn him into a dragon.
Making him a failed pawn of Bran's or a misunderstood viewer of the big picture would be shoehorning in a very rickety answer to something which wasn't a mystery in the first place.
Why would Bran do this? - if it was a mistake, then it would be dramatically unsatisfying and very cursory. Aerys - a lunatic - had more than enough motivation to act the way he did without being worried about the White Walkers. And if he was worrying about the White Walkers, he wouldn't act like that.
