Facial Fat Transfer & Weight Gain

I am considering getting a fat transfer to the anatomical buccal space (under the muscle) to correct an unnecessary buccal fat removal. I fear though that the fat will grow unnaturally if I gain significant weight (over 10 pounds). Considering I'm in my early 30s, the likelihood of me gaining over 10 pounds sometime in the rest of my lifetime is quite high. Would this definitely cause unnatural looking hypertrophy? If so, would there be a way to correct it?
