New mods that need created

is it possible to create a mod that puts your weapon as a slot like your armor an puts it as if it were sheathed and visible on the hip of the character when not in use and in your hand as normal when being used same with a bow but on your back or be able to place swords on your back even if they couldn’t be used maybe just a prop as part of a skin

actually there is a mod for that as for the slot, i think theres an RPG overhaul for that one, im not sure since i used it in a modpack
