My hope is the Lore Update comes before or around the same time as the rest of Story Progression/Neighborhood Stories, so we can see how this impacts autonomy amongst the premades.
I think (hope) they'll add elements from patches and all packs to all the premades (homed and homeless), but obviously they wouldn't show up on those sims unless you have the pack.
Example: Mortimer Goth.
In previous games he was a Scientist, but the career came with BG. Maybe he is taking a sabbatical from that in TS4. He could be given the hidden "Was_Scientist" trait, and have unlocked some of the inventions. This would allow him to experiment in his basement and rejoin the Scientist career with some progress if GTW is installed. I would also expect him to have skills for Logic/Writing.
He might have a (or more than one) degree in Physics or some other subject, this would allow a career jump to a few choices of career with DU installed, putting him at a more suitable income level for someone in the Adult life stage.
He would more than likely have the Indoorsy lifestyle with SE installed (both Writing and Science are indoors) which would suit someone of such a pasty complexion. I also think he may be a bit of a luddite and a Technophobe, as the house has no modern technology, even the kitchen has a wood-burning stove and an old ice box.
The whole family is well-known and well-established since the original Sims game, and are well-known pillars of the community. For this reason, I think they would have at least some level of Fame with GF installed, even if it's only a couple of stars. They would also have a Good Reputation, unlike the Landgraabs, who are more infamous.
Sentiment-wise I think there would be some kind of rivalry between Nancy Landgraab and Mortimer Goth (the heads of household) due to the latter's unscrupulous business practices and monopoly being a bad thing in a small town.
The Goths always had a family graveyard in previous games, with old family ghosts added. As ghosts didn't come until a patch, I would hope to see their home and family tree updated with the tombstones/urns of family members and have the ghosts be premades too.
For Preferences, I would assume he Likes Black and Red, maybe has a preference for Classical Music (he owns a piano) and enjoys Logic (missing Preference) due to his Science days. Writing could also be a Preference. With DHD he would probably have a Preference for Queen Anne style furniture.
