Is this outcome possible for me? Currently a 12B looking to go to a full 12C.

Hi! I'm 20 years old and am currently looking into getting a breast augmentation. So far, I've been recommended either round or tear drop implants either placed either sub glandular or dual plane. I'm aware that I have a a degree of ptosis on each breast, given in the last three years I've lost over 45 kilos. (Though I seem to be borderline 1 & 2) Though I know a lift is more then likely the ideal solution, I'd like to delay having one until after I'm done having children (so around my 30's), rather then undergoing the procedure twice and dealing with excessive scarring. While I'm not after super perky breasts, I'd like to achieve something more natural and full compared to my deflated 12B cup. Ideally I'd like to go to a full C, but I'm willing to go to a small-mid D as well given this is what I was prior to my weight loss. I was just wondering if anybody thought that I may be able to achieve a look similar to some of the examples I provided? The first image is a series of my own breast, and the second is my ideal before/after results.
