OK, this may be somewhat tenuous but
in Parting of the Ways, Rose saves the Doctor because she has the vortex in her head. In the Big Bang, Amy can restore the Doctor (and her parents) because she has had the universe flowing into her head/dreams from the crack.
in Doomsday, the Doctor saves the world by sucking the Daleks and Cybermen into the void which seals the hole through which they came and is threatening the universe, in the Big Bang, he saves the universe by himself stepping into the void through the cracks and hence allowing them to close.
in Last of the Timelords, the Doctor is restored by everyone thinking of the Doctor, in the Big Bang, the Doctor is restored by Amy thinking of the Doctor/TARDIS
in Journeys End, we have two Doctors at the same time, in the Big Bang we have two Doctors at the same time (one distracting the dalek, whilst the other wires the vortex manipulator into the pandorica).
