From the questions you posit the first things that comes to mind is the famous line form Monique Wittigs’ Le Guerilleres  “… and if failing to remember, invent.” or as Ruth Barrett put it in Invocation to Free Women “ .. we have come and we were born to do our own myth making..” 

The Dianic community/ “Feminist Wicce” has a long tradition of reclaiming myths, since myth is in not historic and is suppose to express the essential truth of existence and beyond. 

An example of this is the retelling of the Kore/Persephone/Demeter myth, mothers and daughters. Two different ritual interpretations, which I’ve participated in could be either to reclaim the power of women through the symbol of the Yoni and the taboo breaking clown Goddess of Baubo. The second is my favorite which leaves out the abduction and rape of Zeus and Hades and speaks directly of the grandmother/mother/daughter bonds, knowledge transmission and the growth of the daughter into woman represented by the Goddesses Hecate, Demeter and Kore/Persephone.

This reminds me of the myth that makes Lakshmi and Saraswati into the bickering wives of Visnu which is suppose to explain why prosperity & wisdom cannot be “under the same roof”. This has always bothered me because it limits the meaning of prosperity and wisdom by making Lakshmi and Saraswati weak-minded women in need of a strong paternalistic hand plus it reinforces the notion of women as commodities.

Thank you for the thought provoking questions. I feel a new myth brewing. 

Blessed Be
