Weight changes and fat grafts
From what has been observed in other body sites, large weight gain or loss may result in enlargement or shrinkage of the surviving fat grafts. The amount of change however, is not predictable.
Fat injections to the breast is gaining more popularity in the U.S. compared with a decade ago, but it still is considered controversial. Your theory of greater density of fat cells after dieting and transferring more fat cells with the same volume makes perfect sense but has not been studied to reveal a conclusion.

Fat transfer to the breast
In answer to your specific question, the fat cells which are successfully transferred to the breast will behave just as the other fat cells in your body. As you gain weight they will store more fat and the breast will grow. As you lose weight they will store less fat and the breast size will decrease.
Generally speaking 50-60% of the fat transferred survives. Discuss this degree of augmentation with your surgeon so that you have realistic expectations and will achieve your desired goals.

Fat transfer to breasts
Currently in the US, fat transfer for breast augmentation is still being studied and isn't widely done. We do use it quite often for buttock augmentation and for revisions of prior breast surgeries, as well as for facial rejuvenation. Fat transfer simply moves living fat into another body area. A portion of the transferred fat (likely not all of it) will remain in the new area and will act just like fat in any other body area. As you gain and lose weight, the transferred fat will change in size.
