>>62160113Oh yeah, you totally could. It would take a lot of research and testing to find and isolate genes that are associated with the desirable female traits and then work with a genome editing system in order to splice the desired phenotypes into zygotes that you could then implant into moms, but it's completely possible. The issue would be getting funding, finding a place where such a process would be legal and then improving the efficiency of the process so that the majority of the embryos you made would actually survive.
In theory you could also go about it in a more natural (but slower) way and use selective breeding for several generations. Using those methods for Female X Female pregnancy, you could hypothetically match highly feminine women together and have them conceive children. Then you could take the most feminine girls from those families and have them have kids once they were adults with other women who were raised by *their* two super feminine moms and were the most feminine. Over time you'd eventually produce offspring that are notably more feminine than anything that could be produced naturally.
But of course, there is a threshold where excessive traits stop being attractive. If you just endlessly made wider hipped, bigger boobed and thicker butted women, eventually it would just start looking unnatural and strange. Or you'd run into "the Pug Problem" where a selectively bred subspecies is bred for traits so at odds with general day to day survival that you end up creating something that has massive unexpected health issues. So for instance, the wider hips of females are notably more likely to fracture than the pelvises of males, as well as females being more predisposed to osteoporosis. So if you just kept selecting for women with wider and wider birthing hips, you'd end up with a girl who might shatter her pelvis the first time she tried to get intimate, which is obviously not a good thing.
