Honestly I think the only part that really will need any update is what qualifies as a level 0 spell, since in pathfinder most classes can cast prepared 0 level spells all they want and the 0 level stuff in BoVD isn't balanced around that.

I have this mental image of Sujurak almost doing a parody scene of a Disney Princess, doing some big (and fairly macabre) song number, and instead of woodland animals flitting around, it's reanimated shrunken heads that are bouncing and rolling around and gibbering madly, and the little hoodoo spirits dancing about and diving in to masks and stuff to possess them and make them sing backup lines.
