I agree with your opinion that her voice is amazing.
But I heard the sample voice of the FDG in the video, and the content of her dialogue had nothing to do with WoWs.
She says, for example,
"Hey, boy, if you can't sleep, I'll play a lullaby.",
"What do you want? wealth? honor? or eternal youth?".
In other words, her voices are not practical to use for WoWs mod.
When making voice mods, I also make sure that the meaning of voice is suitable for WOWs battles.
It is impossible to use her voice to create mod suitable for WoWs.
