The Most Awesome Thing That Could Ever Happen in Doctor Who History

So, it's a known fact that Doctor Who, along with all other fiction, is 100% true in a parallel universe. But, what if certain elements of the plot line are still true in this universe? Specifically, I'm hoping for the part where the 10th Doctor runs the torch into the Olympic Games. I'm not sure if it's possible for a modified version of fiction to be true in this universe, but it still might be possible for that scene to happen. I'm hoping it will.
