Have miasma clouds from rotting corpes include chems from the body

[KikiMofo]

this does mean that if you killed someone with phlogistion poison they'd give off burning clouds of fire as they rotted. and ling victims would likely give off a bunch of neurotoxin...

sounds funny and silly and sometimes very very deadly

Do husks give off miasma? They would be dry husks and I don't think that would rot or miasma.
