Well what are you talking about ?
Is it the pointing of the nips more inwardly, with the same position ?
Or are you talking about a change of position to a more central place ?
In very small amounts a massage might help.
And a massage might be helpful in general to help avoid hardening of tissue.
You might also look up if the training of muscles underneath would change something.
There are special exercises for training exact muscles.
To be sure talk all of this through with a doc.
Otherwise a real big change would need a revision
Well there is alot of variance with boobs ... so could you be happy with it anyways ?
Its not uncommon that inlays shift some, if you look up pictures of outcomes there are quite a few imo who have this.
The guys like it in any case ... I'd say

BTW a drawing should not be against the rules.
Like indicating a point and indicating where you would like to have it moved. Someone did that with questions about SRS revisions.
But if its a change to a more central place it should be clear.
