One, there is a tool called Loot to sort the load order for you. That "load order" you posted will not work because for example, Jaysus Swords is an esm, which means that it has to go near the top. Doesn't matter what comes below it. It's going to go up top or the game crashes. These mods also have patches, leveled lists and bashed patches which make them play nice together. For example, I do have Immersive Weapons, Lore Weapon Expansion, Heavy Armory, Dawnguard Arsenal, and Jaysus Swords in my load order. However, thanks to making a bashed patch, they play nicely and any enemy I encounter will have a random chance of bearing a weapon from either of those mods. For example, I walked near Helgen to see an Imperial Patrol (from Immersive Patrols) fight a group of bandits. The bandits lost, and on looting I found one was carrying a war hammer from Heavy Armory, another was carrying some sword from Immersive Weapons, and another carrying some cyrodillic blade from Lore Weapon Expansion. Insanity's weapons are just retextures, so with the Matorsmash tool, you can actually turn them from separate mods into one big mod. I have a 500 mod build centered around Legacy of the Dragonborn and several quests, despite the game having only a limit of 255 plugins (I'm WAAAY beyond that) thanks to these tools of merging.
