Can you advise on expectations of decreasing nipple size? (Photos)

I have breast feed soon to be 4 babies. My nipples have increased in size and darkness of color. I want to reduce the size of nipples and how far they extend. I’m not sure if I want areola surgery as I want a breast implants and feel after boobs increase in size my nipples wil look more proportional. I am extremely scared of decreasing sensitivity in nipples after surgery. Losing feeling sensation in them. Also them looking unnatural or worse in appearance.
