I was looking through screenshots wondering if I should take the time to add more pics of this house, and remembered this thrilling moment. A stormy night, an equally stormy Agnes... and a cloning machine. I had to test. We can't clone special sims like Guidry or Temperance (I've tried, their special trait prevents it).
So the main project is, or was, building Cordelia's Cottage into something fit for her when she moves in. I was doing the GTW science career anyway because some quality-of-life items are from the GTW science career, like the illness-curing shower, and when there's a full house it's more of a pain to do the active careers. It's still such a good first move. Clone age-away serums. Clone potions of immortality that you bought on Plopsy. Clone slimify serums to help a townie out. Clone money plant seeds. It wasn't out of my sim's way to test this.
Yes, you can clone Agnes. I got Martha Crumplebottom, which is a remarkably on-brand name. I aged Martha down, moved her in with Vlad, and lo! a Crumplebottom family without messing with the assigned roles of Agatha or Agnes.
*I know the Vlad + Crumplebottom baby was born, but that's happened off stage. I don't even know the gender or name.

Postscript:
It's a boy, Sam Crumplebottom. The game put him in the crypt! lols
Nah, he'll be right. He'll grow up just fine.
