The fact that you are asking the question suggests that you are not comfortable with adding a second story that does not match the first story brick course. It is difficult to know without seeing the property, however, i would tell you to trust your own instinct and ask for advise from someone in the industry that you TRUST. Please, don't ask a contractor that you just met to make this decision....trust your own eye!
Thank for Asking!!
