I've done a thing like that on Empire. But it's not coded.
I've just added a php script on my server's website that move the corpse to a zone that I've called The Sanctuary (it must be a dynamic zone). Once the corpse is moved, the character can zone in (that will bootup the zone so the corpse will appear) and can loot it, then he will leave the zone.
Ghetto way but it's working

ps: if you want the script, just ask.
