>>6010555We would need the soul. If the stone is down there waiting to retrieved, maybe a tiny chance, assuming it actually shows you a persons spirit, not some imitation. Irkalla did say that this place could "move and repair" and it can create the body, naturally.
It would depend on if there is a means to retrieve a spirit we can find.
We know there is some means or series of events that can let Helga and the gang returning, but their deaths were kind of odd.
Also, gonna emphasize the 'repair' part, considering we have a LOT of Merlin pieces in one place.
