I think that would be a great idea. Those books have inspired many a thought sessions on how one might play that in a d&d or Pathfinder setting. It would most likely bring an aspect into the game that really hasn't been covered before. It has the feel of a Bardic class, or a Necromancer class, or even a class that binds extraplanar creatures to bells to be used for a specific purpose. I feel that it would be an interesting way to tie in an idea given in a book setting into the role-play setting.
