Not that I hope Kyouka would turn out to be Layla (regular Layla/ Future Layla/ Past Layla/ Edolas Layla or any other variation of Layla for that matter), but if Franmalth can still obtain a soul from a dead body which just got blasted, killed and terminated by the most powerful mage of all times, then I dare say that the logic of Tartarus not being interested in someone with poor health isn't valid.

Besides if Tartarus want to get "back to where Zeref is", it may make sense that they would also search for the One Magic which is in some way connected to him. Therefore they could turn their attention towards someone who might know something about it, regardless of said person's health.

However, allow me to once again state that I would hate it if Kyouka is Layla due to the same reasons why I would hate it if Silver is confirmed to be Gray's dad: it would lead to sobby backflashes and the Demon parent would once again become "good" in order to save the child from doom and then die after saying some cheesy goodbye words.
