That's an interesting question – this mod includes a few different types of edits to different sims, some of which would be compatible with that and others which would clash.
- I edited the Goths, Calientes, Pancakes, Landgraabs, BFFs, Roomies, the Spencer-Kim-Lewis family, Johnny Zest, Alex Moyer, and the Grim Reaper from the base game using Denton 47’s tool. I also edited the Specter household from Life and Death.
- For these sims, their household files (the files Denton’s tool creates as “HH” packages) were overriden, which isn’t compatible with other overrides. These edits include the edits to the sim designs, hot and cold weather outfits, new skills, new traits, likes/dislikes and romantic preferences, etc.
- I’ve also added new NPCs using Denton47’s tool via an override of the Sylvan Glade region description. This is compatible with anything that doesn’t override that description.
- Other edits to base game sims, new sims, and sims from other DLCs were done using loots from a premade sim relationship file that runs on new save start. This includes some types of fixups to sims (milestones, Parenthood characteristics like responsibility, occult powers in some cases) as well as the relationships between different sims. These edits require their premade sim and household templates to work correctly, which doesn’t exist for base game sims unless you add them via Denton47’s tool.
You can safely make edits to any sim outside of the ones mentioned above. I’ve also added fixups to Vladislaus Straud, Caleb and Lilith Vatore, Guidry and Temperance, and Lady Ravendancer Goth through the relationship loots – as long as you keep their original premade sim templates and household templates these will work even if you override their household files via Denton’s tool.
I might make overrides of the Get Together sims at some point, too, since their randomized outfits are always terrible, but that's a bit lower on my priority list and it'd probably be a separate package anyways.
