"Against nature" can mean either "beyond nature" or "beneath nature." The Romans 1 context is a list of sins, hence "beneath nature." (Compare Hays [1986].) In Romans 11:24 is a statement that grafting a wild branch into a cultivated tree is against nature. You would be more precise to say that God, in grafting gentiles into the Jewish tree, is acting in a way analogous to something that is against nature, in this case clearly beyond nature.
