The majority of the heat in peppers comes from two parts of the pepper: the seeds and the ribs. The ribs of a pepper are the white part inside the peppers that the seeds are attached to. If you remove those parts from the peppers, you’ll reduce the heat immensely. Do this for all of the peppers and you'll have a super mild hot sauce. Another way to reduce the heat is to replace some of the hot peppers with red bell peppers or even those mini sweet red, orange, or yellow peppers.
