Devouring Totem and ES recharge

I was wondering - can devouring totem somehow restore ES?
Zealot's Oath would probably not work, since DT does not increase life regeneration but leeches life (or so the skill's text says) and mana to you.
What about Ghost Reaver, though? Has anyone tried that? It's actually not you but the totem that leeches, so it probably won't work. But before I make a char just to test it, does anyone know if it works?
