Seeking symbol

[Nimbikarana]

Hi. I've just started worshipping Venus Castina, the goddess who comforts female souls trapped in male bodies. I now need a symbol for her. The Mars-Venus sign isn't what i'm looking for. Any kind of stylized thing would be cool, something suitably gender-ambiguous or gender-transformative. Thanks. Reposted at main board for extra traffic.

Perhaps this is a good place to start?
