Not trying to be nasty here at all, but this overwrites a massive amount of base scenes. none of mine that are published anyway, but it will affect "better pregnancy" and quite a few of my own mods that I havent released, So I cannot use it. I understand where you are coming from, and that there is no better way of doing this. However you could prefix your files, that would let your files and the base ones run, but your files wont be called all the time. Thats the only real suggestion I would have. But this isnt going to be compatible with a lot of stuff soon. Including one I will soon be releasing that controls the amount of npc's in the game. This will force people to choose who's mod they run! In my case this isnt an issue, "my population mod" already is patched for "better pregnancy" and I could probabily do the same for yours, or even let you have details on how to patch it for pregnancy. I will have to consult the author of that mod first though.
Still nice idea and I hope you continue, the more mods the better.
And if you continue and want suggestions for V2 how about naked npc's as well lol.
Added FYI this will also not work properly with "the new goodbye mod"
