Morticia has the most "extra" content of any character in the game. In total, I have added 9 extra scenes for her (including Ballfondlers, which has been mostly redone at this point) that aren't in the Unity version of the game, and boosted her presence significantly, and re-wrote a lot of her character.
9 Scenes may not seem like that many, in a game with so much content, but the next closest character with extra scenes is Beth. She has 2 scenes not in the original. And Morticia only has 31 "sexy" scenes in total, again, 9 of which aren't in the original. Compared that with Summer at 41 or Beth at 37 (and for anyone wondering, Tricia is the next highest at 23, then Jessica at with sad 16).
So, yeah, I added a lot of her into the game, and I'll most likely keep adding more of her. A date is not impossible, pretty much every other main character has had one Movies and Mall for Summer, Anniversary Dinner for Beth, Jessica gets and actual date at Bips and Chitz... Tricia get a wedding, sort of, not really a date, I guess she is missing one too, but it would be a new scene and won't be high on my priority list.
I can add a "Morticia Date" onto the request list, but again new scene, and I tend not to do many new scenes. This isn't a traditional game. My goal each update isn't to make new content, it's to bring content from the Unity version into this Renpy version. The fact that any new scenes get done at all honestly boggles my mind.
