Would I benefit from an implant replacement/revision?

The first doctors suggestion is reasonable. The issue is better understanding your true shape desires.

Another option is removal, wise pattern lift and delayed augmentation to give an even more youthful look.

There are several variables going on at the same time, and rather than thinking of revision surgery as one procedure to break it into it. It’s different sub components.
A Lyft has certain dropbox, but would put your nipple position in the more ideal location back up on your breast. Your breast do you say fairly far apart on your chest wall. Considering that, the choice of high profile implants may not be ideal. Widening the diameter of your breast, especially towards the midline with the use of wider lower profile implant may suit your body shape better.
I don’t see a really strong indication for having a revision surgery. Your breast sit on your chest wall where they always did, and having augmentation doesn’t move the breast position. If anything implants can over, emphasize breast anomalies like breast divergence.
If a moderate change justifies having revision surgery then maybe it’s worth it.
I generally encourage people to have multiple in person consultations before scheduling surgery. Nothing wrong with getting a few more opinions..
Understanding your own candidacy for the procedure is a big part of maintaining long-term satisfaction from plastic surgery outcomes. Understanding your candidacy includes understanding the inherent limitation of any one surgical procedure with a good understanding of what the procedure can, and cannot accomplish. Women who have divergent breast or breast that sit far apart on the chest wall should ideally have had a discussion about this during the initial consultation.
