How advisable would it be to take contraceptives to enlarge the breasts?
I think you'd have more luck using topical estrogen cream.. but it doesn't come without risk:
This 50-year-old gentleman had developed some unusual symptoms gradually over several years: reduced libido, smaller testicles, breast growth. When tested, his testosterone levels were low. It turned out that the embalming fluid he was using (without gloves) contained estrogenic compounds that were being absorbed through his skin. They were disrupting his hormonal balance. This was published in The New England Journal of Medicine, April 14, 1988.

As always, don't use any hormone without doctor supervision if possible. Especially if you are playing it fast and loose with the dosages.
