I play with your mod for the latest 0.17 - so i don't know if its the case still so.
I would suggest to use a 'smelting' recipe for the corpses.
Albeit its not a super big problem to build a assembler contraption for each corps, but as the output of each corps is more or less the same i would find it better to use a smelter/furnace for the deconstruction of the corpses......
