uhh... what do you mean by "revive her". Even if your logic of Erza being an enchantment is true, what does that have to do with anything? As for the Neinhart thing, sure he can do that... but that's so lengthy. It seems weird for Zeref to go through so much to order Neinhart to use his magic to summon something, then for that summoned being (Kyouka) to use her ability. If that was simply a remark, disregard what I said above. Now for Erza being an enchantment, why go through such lengths to order her subordinate to kill something she can easily kill later? Also by the way Neinhart refers to her as "Lady Erza", she is likely an important figure (than just an enchantment). Erza has been through life or death situations many times, and ran out of magic (Edolas) but hasn't reverted to an object or anything. Also, for Irene to maintain such a high caliber magic user for years and not know where she was; who happens to have similar appearances... not likely.
