This might overlap too much with the stuff you're currently using, but, In the game Dead Space...
[sblock]The monsters are Necro-recombinators. They take dead flesh and assimilate it, or reshape it into new forms. It's very much "making organic monsters with dead flesh", because they breathe and bleed and such. (Although there is one monster that literally sticks a probosis into the brains of corpses, re-animating them into suped up brutes). The flesh is also taken and converted into cocoon-like structures, or organic stuff that grows everywhere, making the environment more accommodating for the monsters.
In general, in order to kill the monsters, you have to actually sever their limbs.
It's more involved (a hive mind monster, an artifact that draws the influence of the hive mind, etc), but you get the jist. It would be suitable for an aberration species, or at least an aberrant entity.[/sblock]
