Keeping them from attacking would require...Hey can those Wraith become our friends? That would be cool. Like if they have no reason to be hostile then maybe we can turn them to our side.
...Between ensuring they don't remember that they should be hostile, and keeping them fed adequately on your Magic... I think roughly 4 successes each per turn.
Though you'd get an immediate project to see if you could Connect to them fully and convince them to work for you now. Which, if successful, would naturally reduce it to 2 successes each per turn, and that would get the benefit of... probably your Growth bonus.
So, short-term quite expensive, but long-term actually quite feasible. IF you want to invest the resources.
Dire Bats are considerably cheaper to contain and feed, FYI.
