actually resurrecting people would be the tricky part.....whatever you do with them after that shouldnt be a problem for ANY sannin
especially one who can heal things, like tsunade

its like a permanent henge of a sacrificed person into someone else, judging from the looks of tsunade without her cover-up, i'd say she doesnt look a whole lot better herself [img]i/expressions/face-icon-small-smile.gif[/img]
