I'm guessing there's no chance of matryoshka vore? Like the layered dolls I mean.
Just kind of popped in my head really but if you're up for running with it then who am I to stop you?
I've been through some vore fiction and I just barely remember seeing examples of that.
A few of them have had methods of reformation or respawning but those are a little too fantastical or sci-fi I imagine. There was also this one fictional "prey" race that evolved immunity to digestion... except by each other.
