A numerical model like this is cool, but personally I think it can never be proved. How to prove or dis-prove geological theories about the detailed earth evolution on the scale of millions to billions of years is a big challenge.

Testing the parts that supposedly came from the planet and comparing them to the moon would provide a lot of evidence for or against this theory. It can never be proven, but that's not the end goal anyway.
