There's nothing I know of that makes storing a person's soul into an item -not possible.-
With that being said, manipulating souls in the Aetherstream seems to be reserved for very powerful beings like the Elementals, or White Mages working very closely with them.
We also see an uber experienced Alchemist dedicate years to bringing someone long since gone, and he's successful... briefly.
So with that said, I would say it's possible but... you'd need to adjust the power level of whoever is performing this to be on par or above those people I just mentioned. Near legendary power levels.
