French/German Voices w English Text; What Stops Us?

[Live2sculpt]

I have recently, roughly, understood that the Wwise tool and .wem creation process is much more complicated than the good old days when you could just import your own sound files. Hence the existence of only a handful of Music Mods having ever been made.

Still, can someone with a little knowlege explain what I'd come up against if I tried to: A. Back up my French loc audio files. B. Re-install my English loc files. C. Use PFM to replace my English voice files with the French ones? At first glance I'm not seeing any associated bnk files in the French localization, so I'm guessing that the numerical names for the French voice wem files match their English counterparts.

I've probably overlooked a .bnk or other coded file in the French localization, which is specific to the French wem files. OR, maybe I'm misunderstanding how a .wem file works. Otherwise, I'd have expected this approach I'm asking about would've been done by someone else long before now. I've looked for information on this and nobody seems to have discussed it yet. Which I find hard to beleive.

Any knowledgeable answers or insights?

ps: I should add, that if I find out that this task IS doable (without hex-code or such labors), then I'll probably make that mod. First in French, and then, if possible, also using German.

Thanks!
