You need much more information (as does your chosen plastic surgeon) before considering this line of reasoning and plan of action. Depending on the size of your present implants, whether or not there are any concerns related to the implants (capsules, calcifications, deflation, rupture, etc.) fat grafting may not be an appropriate consideration (even if I did recommend it). I personally do not recommend fat grafting for elective breast augmentation, but am absolutely comfortable with fat grafting for reconstructive or other cosmetic concerns, just NOT into an otherwise normal breast. Some of the grafted fat ALWAYS dies (30-50%), and this dead fat can cause scar tissue or calcifications that can interfere with the mammographic detection of breast cancer. Since you have a 1 in 8 or 9 lifetime risk of developing breast cancer, I would not recommend taking away mammography as a valuable tool in detection of your (possible) breast cancer EARLY. Cost is also usually substantial, and not worth it for minimal enlargement and lumpy and scarred results.Consultation with one or more ABPS-certified plastic surgeons (ASAPS members) would be my best recommendation.
