Problem with the Lifecrafter's is that they're still human, so they probably won't be more affected by Shaper attacks than other Shapers, unless Lifecrafters are re-shaped so many times that they are more essence/creation than actual humans.
It probably won't be in there, but if you're a rebel and want to work for the Shapers, it would be nice if you could calm your anger like what Lilitalia did in G4 and practice being human again... but then, that would defeat the themes of the canisters: to gain power, will you sacrifice your sanity?
