If anybody's having trouble modding existing wives, they should reach out to me and I can make tweaks as needed to the wife's core script to allow their mod to tie into it.
Adding new wives is even easier. All they need to do is exactly what I do: write the story and add the photos. There's zero core coding changes required, the game is totally drop in a new wife script and go. The engine doesn't care whether I wrote the script or somebody else did.
a4hryou even created a sample template with the basic coding in place to help get people started. Again, if people have questions about something they're finding challenging, the best thing they can do is ask. There's lots of people here who can help with "how do I do this?" questions."
