I don't think that will work. The manual says the following about HurtFall:
Quote: "Sets the distance beyond which a fall will hurt the entity
or player. A value of zero means any vertical landing will
hurt, where a value of 200 means the player can safely
drop two layers before it will hurt."
First, they would have to actually fall, not just spawn dead, and the "hurt" might not be enough to kill them if they did in fact fall.
Setting the animate property to 60 (Laying Spawn) or 61 (Laying Idle) and make them immobile might work better.
