I have no personal experience, but it sounds like it should help.
Surferjoe suggested me to use PC and I tought to use it (I was totally flat, then with SP I gain something like man boobs and progesterone should help with conical boobs) but then I had my hormonal results and my E/P ratio was 59 (it was ok becuase I was in my lutheal phase) so I decide to avoid it.
You should be careful when you use only estrogens or only progesterone, to avoid dominance. I suggest you to use a PC with an easy way to dose it.
