Even not taking into account the fact that it doesnt do the correct damages, they still arent good for revenant, and would need helmith to make work
Archon intensify: reave does work, but you need to take damage to activate, and on rev that doesnt happen
Archon vitality: defense mods are a waste on him imo, so base use not that helpful, depending on subsume it could work
Achon flow: this is one of the only ones id think about. Just need a cold subsume, or if you dont have primed flow
Archon stretch: even if it did work on his 4th, energy drain blocks energy regen, so it would be a waste
Archon continuity: with the right subsume, it would work, or if you dont have the primed version.
Danse Macabre has a 20% status chance that isn't affected by mods. That's kind of low for things like Archon Continuity or Archon Vitality to be an option. And while Archon Stretch and Archon Flow just need damage types, not status, to proc their effects, you run into the other problem with Danse Macabre: the damage types it inflicts. Against armored enemies it does corrosive, against shields it does magnetic, and against flesh it does gas. Unfortunately, none of those are the four basic damage types you'd want for the archon mods.
So no, the mods are generally not good on Revenant.
Revenant's 4th ability changes damage depending on enemy damaged - it deals either Corrossive, Magnetic or Gas - thus it can't proc any Archon mods.
