Here's my 2cents:
I don't think it would work. I'm not convinced that they are living. Even with the text scion posted on the first page For the intent argument, I suspect that they meant living as acting thinking, not in the game term living.
Actually there is no game term living, so that leaves it up to interpretation. I would group living: aberration, animal, dragon, fey, giant, humonoid, magical beast, monstous humanoid, ooze, outsider, plant, vermin. Not living: Construct, Elemental, Undead. Water elementals being the exception worth noting. It's hard to believe with spells that have targer living creature it's not defined, I must be missing it while I fall asleep and write this.
The last argument is a bit of childish semantics, but they specify how it is different from other living creatures, but don't specify that it is a living creatures or suseptable to spells which affect living creatures. Not really a good argument, if someone can find a game clarification of living creatures, I wouldn't try to defend this last point.
