I think the setup that would work best is with the Prefab version installed, then using the patcher from the Ikea version to generate enchanted versions of modded weapons (if desired) and removing any duplicate enchanted versions of vanilla weapons from the patch plugin if present. There are also multiple overlapping statics in the Silent Moons Camp area, two versions of the same quest running at the same time, and so on. Right now we have two different Lunar Enchantment versions of every vanilla weapon, one from Serenity.esp and one from LunarWeapons.esp. The Ikea version comes with one plugin for a minor edit to the camp, without all the features of the major camp overhaul (SailorMoonClub.esp), and another plugin, LunarWeapons.esp, which is only supposed to be used if you are using the Ikea version without running the patcher to generate Lunar-enchantment versions of all your non-vanilla weapons.
The Prefab version (Serenity.esp) comes with new versions of the vanilla weapons with the Lunar Forge enchantments merged into the one file. Serenity.esp, SailorMoonClub,esp, and LunarWeapons.esp are all installed and enabled, but you're only supposed to have either the Prefab or the Ikea version of the mod, not both. Multiple versions of the mod Serenity - A Silent Moons Camp Overhaul are installed.
