Expanders making breasts farther apart (photo)

Hi, I had a preventative double mastectomy. I have had all my fills, and am waiting for my exchange surgery. As I have gotten my fills my right nipple has moved further down and become less symmetric. I also feel like the space between my breasts has gotten larger. Ideally I would like my breasts to be closer together ,.Are these things that can be fixed at the exchange surgery? Also I have the option of more fills, does the size I am now look proportional to my body.
