I might as well just post it here in case anyone else wants to.
Basically, what I did is follow this video to find out how to rip the right files from a Wild World rom:
Since this method requires Windows and is a bit confusing, I'll upload the ripped and converted files here:

(I don't think that sharing them is illigal, but if it does get taken down then just follow the video and rip out your own .dls)
Next, download Sforzando (Windows and Mac):
http://www.plogue.com/products/sforzando/
and you should be able to open up the .sfz files that I uploaded. If you ripped the .dls yourself, just tell Sforzando to import the file and it'll generate the .sfz files itself.
Also, since the soundfonts for the different KK vocalbles are all in separate .sfz files, I made a custom instrument rack preset for Live users (check the hint box in the lower left of Live for the macro knob value for each syllable):
