Is it possible to add EvilCraft to the intergration? EvilCraft has blood and ghosts (in mod called Vengeance Spirits) left behind when you kill entities and can shove them into Spirit Furnaces to harvest drops indefinitely as long as you have enough blood to fuel the furnace.

Would it be possible to make Vampirism mobs drop stuff in the Spirit Furnace and, on your call, make both mods' blood both fuel and edible? I.e drinking blood harvested from undead trees, killing mobs, and random condensed blood items in dungeon chests or powering the machines with blood you suck out of hearts or other mobs when you bite them.
