helz, the campaigns from Armageddon's Blade are added to The Shadow of Death with a patch that unlocks the Conflux, in a version that weighs 2.6 MB: there are 2 non-empty files.
But I don't see the point for you, because the difficulty is forcibly set in The Shadow of Death.
If you want impossible difficulty, play single-player maps: there you can choose the difficulty.
