I suggest several points to consider: 1) Nipple inversion is common and usually benign and harmless, but occasionally it can be a sign of breast cancer, so have it evaluated first. 2) Breast implants, whether they are saline or gel filled, will provide a platform of support behind the nipple and areola. This can improve projection for lax or sagging nipples, but doesn't correct the actual inversion. They will often look better after augmentation. 3) Your surgeon can provide a procedure to correct the actual inversion. This stretches or divides the shortened ducts and fibrous tissue and restores a natural appearance. The procedure does not assure breast feeding, so you may want to delay it. The procedure can be done by itself, under local anesthesia, or at the time of your augmentation.
