What if ?? ...no ??

I don't think Signora will ever be revived, but if it happens, it would probably be in Snezhnaya, not Nod-Krai

i hope not

At this point it's been so long since she got killed that they would need to take the time to reintroduce her character, give her new motivations, and she'd get curbstomped by the cast of friends we now have with insane levels of power. So, no lol
