I'm confused. You found a mod that returns things you want to Survival, but instead rather bring Hardcore things to Very Hard? Sounds like you got what you want. But this probably won't happen as Survival items, such as food, diseases, are regulated by a quest. To do what you'd want, one would have to rebuild Survival from the ground up. Your best bet, would be do find/use/create mods that make Survival more of the way you want it.
