Larger with cleavage and to fold over slightly to help cover my scar. What CC replacement or adjustments do I need? (Photos)

I under went lipo, tummy tuck, breast lift and reduction. however after the breast reduction they were too small and saggy. So I had 360cc high round implants inserted. (that was the largest they could do at the time due to them removing so much skin and breast tissue when they reduced my original breasts. I'm not happy with them at the moment. I want them to be a little larger with cleavage and to fold over slightly to help cover my scar. What would be the recommended cc size to replace them to achieve this? (once my skin has stretched and can accommodate bigger ones). The first picture is how they look now. the second picture is AI of how I want them to look.
