After everything we've seen in Bleach, I'd say anything's possible when Mayuri's got a finger in the game.

Revealing that Mayuri collected her corpse and resurrected her would be the perfect chance to bring her back into the war and properly show off her combat skills and her Bankai. Who knows, maybe Kubo even planned that along with the whole zombie and zombiefy thing when he killed her off.
