That's definitely a good plan! I always suggest a mixture of breeds for a first flock. That way you know what you like and what you don't. Our advice can only get you so far, as it's only your own personal preferences that can decide which breed works best for you.
I don't think I could ever have a single breed flock. When I got my first ladies, I went through and took one out of each bin at the farm store! I had a little less luck keeping in the leghorns and California whites though.
