hmm... i don't think so... If healomancers had resurection spells then there wouldn't be such a sense of fatality around croaking. Further, one of the written updates is from the point of view of a healomancer showing that resurection is out of his reach.
Perhaps a tri-caster-link of a healomancer, thinkamancer and a croakmancer could perform it, sort of like a decryption but without all the evilness, mind controlling, propension to being dusted and the side-changing. But ther's no faction we know with all those three, and no one in erfworld likes to get casters into combat.
Also the links are mostly unexplored magic, so it isn't likely to have been done before... and with the juice cost adjusted to a three caster spell, resurrecting or decrypting units would loose it's atractiveness when facing Wanda who can do it for free. They'd be better off using such a link to find ways to kill as many decrypted as posible.
