I don’t think mixing a lot of herbs with the same action is a good idea.
Your aim shouldn’t be to reach a very very low testosterone, this is bad for estrogens production. 
You can mix SP and licorice (because licorice raise your estrogens and lowers your T) 
Don’t try with a lot of herbs at first, try with one herb and see if it works, then you can add other herbs for hormonal balance. 

For example: try SP, if it works add licorice 

I think a good combo is: an anti-androgen + estrogenic herb in follicular + vitex in lutheal (just if u haven’t PCOS) but it’s all about your hormones. For example: if u have estrogen dominance, avoid estrogenic herbs
If u have PCOS use just an antiandrogen 

I m planning to add a pro aromatase in my follicular (not an estrogenic herb because I had a bad experience with PM and other estrogenic herbs didn’t work for me, so, maybe my own estradiol should works better) and vitex or maybe Progesterone cream in my lutheal. 

Use low doses of herbs!!! NBE takes time, not heavy doses of herbs. 
If u overdose you can downregulate your receptors and also go to hormonal imbalance.
