Could Mars itself be the "Mars sized body" that impacted the Earth to form the moon, and the combined gravity effects of Earth and Venus catapulted it to its present orbit?

If everything remelted from the impact, could the Earth, in a way be at an earlier stage in its cooling and that is part of the reason. And could the gravity from such a large moon also keep the Earth hotter and more active?
