This is a really good idea. You should have an item called "Body Bag" or "large Burlap Sack" that you have in your inventory or can equip that lets you pick up one dead body and then move it somewhere else and then drop it. This would be sweet to get rid of a corpse so a guard doesn't walk by and see it etc, and also like you said "clean up the streets" :D It could be a spell too, when cast on a dead body, it teleports them to a specific place. Kinda like the spell that lets you warp to the places you pick with another spell. You cast "drop Body here" spell in a location, then go cast "move body" spell on the dead body, and it would send the body to the place you marked. It would only work on dead bodies, not anything living. Even dead creatures it would work on.
