I don't think that could happen. Because then you would have a purine trying to hydrogen bond with another purine. Purines hydogen bond to pyrimidines and vice versa.....but just to answer your question, For a DNA double helix it will  destabilize and maybe denature. But I am not 100% sure. I am just using my logic and what I learned from biochem class.
