I think that’s a great idea, it could very well be the Triple Goddess. When I went to lay down I was thinking about the 2 of Cups & 2 being duality too. Then abundance, stability, growth, energy, protection, flowing water with the one card being a lighter scene & the other being darker all things that would correlate possibly with Persephone too. She is very much associated with cycles of Spring & retreating after the season has passed to the Underworld & things like protection, abundance, growth, stability, & emotional healing. She has that duality to her.

However, that’s not to negate your feelings because ultimately it’s what you see in the cards for symbols & attributes relating to the deity. If you’ve been drawn to The Triple Goddess already, then there is no harm in reaching out or going deeper in your learning about her. It may be her coming through in ways that you would recognize & not necessarily someone else. Things that would have meaning specific to you.
