You can add the reaper effects using:

sim.add_buff buff_GrimReaper_Role
sim.add_buff buff_GrimReaper_AlwaysOn

Does it matter the order in which you enter the above two commands in?

probably not, but that's the order I did it in. Just to be clear all it does is give you the floating walk animation and the black aura. SimGuru's confirmed there's no reaping action yet. (I found a piemenu category for Death so we'll see)
