There's actually alot of research in this topic. You should look into "Genetic Programming" on scholar.google.com and you'll find some good presentations.

For example https://scholar.google.com/scholar?hl=en&as_sdt=0%2C21&q=gen... and that references a paper where they do this with MUGEN (Ai v Ai fighting game) http://irep.ntu.ac.uk/id/eprint/30021/1/PubSub7423_8186_Mart...

Genetic programming sounds like a complicated term, but it's basically an easy way to take successful characteristics and breed them into something else.
