I know that we have established that Morty resembles Rick a lot (his eyes, his face shape, his nose and his future bald spot) and the gender bend design form (Morticia) is basically the same only with bangs and long hair but I raised you: a Morticia who inherited her grandmother aka Diane's features, from her hairstyle to her nose and freckles. Her face is a bit round but she is 14, maybe her face structure will resemble Diane's as a young woman than a growing teenager.
Honestly, after drawing this I realize this Morticia looks identical to Beth (who if you look at her design has Rick's face shape but Diane's nose, which I applaud the character designer 👏)
This idea comes because I could not help but think about how gentle and protective Rick is towards Beth, any version of her.
Then, I think about a Morty(cia) whose appearance stops Rick dead on his feet. Whose traits of his dead love continuedly passed on from daughter to grandchild. Would Rick have treat that particular grandkid better? Be gentler? Kinder? More protective?
On a lighthearted note, I know he despises that Jerry's brown hair trait beats Beth's blond one.
