Yellel, silhouettes are a great idea! Then it is just a person's head, no details.
However, that raises the question of the card numbers and playing card insets.
Personally, I'd be ok with a deck like this that doesn't have numbers and insets. But they're important to some readers.
Plus, at what point does this deck cease to be an actual Lenormand deck. And do we care?
I love some of your ideas to be more inclusive and for multi people relationships
I own a few Lenormands which have extra cards! I am sure some classical people would be annoyed by it but the system is not set like tarot, I think you can add cards and it works okay! It doesn't matter. I notice though that those decks don't have playing card inserts and just add extra numbers on the extra cards. I actually prefer lenormand without inserts but some people do like to do cartomancy with them. You can also produce alternative versions of the same card so people pick one that fits, just adding to your ideas
My daughter and I have been discussing this for our deck as two spirited people are an important part of our community (and one of my kids is 2 spirited). I draw faceless people anyways which helps. We are including 2 cards with just a shoulders up image. All our images have long hair (male and female) but you could use a gender neutral hair do of another sort.
