You can't have both but do note that you are free to make a subpage of your userpage titling it something like "User:John Smith/Talk" and you can leave a message wall greeting on your wall directing users to your talk page if they so wish. That would probably be the closest solution to having both but also note that message walls are generally easier for users to manage and thus it will be used more frequently than a talk page if the community has the option to both.
