Is It Possible to Order Customized Breast Implants?

I had breast implant revision surgery recently to replace saline implants which visibly wrinkled. I have very little breast tissue and therefore chose the Mentor CPG "gummy bear" implant. These implants even looked more wrinkled from the thicker folds of the shell.The surgeon replaced them 3 days later with an overfilled saline implant. I now have 2 very firm, but not wrinkled, balls on my chest. I am 48. I am 5'6", 118 pounds. According to my surgeon, I have the least breast tissue of everyone he has ever seen. I went from an athletic 32AA to a 34 DDD and I feel way out of proportion. He had to keep filling the shell with saline until there were no visible wrinkles. I was wondering if it is possible to order a custom, more solid gummy bear implant that does not fold when held vertically? Thank you.
