The solution is actually really easy. Just be a good person, and you, like Pinocchio, will get to be a real boy. The Hollow feat has as its prerequisite, not its benefit, that you cannot be of good alignment. As long as you are of good alignment, you lose the 'benefits' of the Hollow feat, which may well include not having a soul, and certainly includes not being able to be raised from the dead.
This is only of use to the demons in question if they've got a way to convince the character to be of good alignment (maybe via Atonement?) before then returning said being to Chaotic Evil alignment after death but before judgement. Otherwise there's not a whole lot of published things they could do (but stuff involving soul gems might be worth a shot).
