Hi guys. I'm doing a little roleplaying here and decided to make a custom cemetery. I found that it was more efficient for me to make a bunch of new households and then just kill them off as opposed to hunting down everyone else in town and making the whole place empty. My worry is, if I force the sim to die (e.g. using NRAAS force kill command or using weapon mods), will ghosts still come out naturally from their tombstones if I place them in my graveyard?

Yes, they will, and the ghosts will be the appropriate colors.
