You should test this before putting all your items into them. Note: some enemies/NPCs are glitched and cannot be revived or cannot have items taken from their ash. Once you get there, your corpse may have turned to ash but this is alright, because now you can take your items from the ash. The second and final part of this is you need to fast travel to any city, whether major or not. This being will follow you for however long you the spell actually lasts (unless you have Dead Thrall which will revive them until they are defeated). Then, resurrect the corpse, which is now holding all of your items.
Since corpses don't have a weight limit, they can carry everything in your inventory and more. Once you've killed it, place all the items you want inside it's corpse. What you have to do is find anything or anyone you can kill (companions if you're desperate but even something as weak and small as a rabbit will do). All you need is to have a Raise Dead spell (higher levels work but the bare minimum is required for this).
