I think the issue with dark is its a normally one of the soft-expression types. This would make her sound very different since her original voicebank is a "solid" type.

Most updates seem to add a "soft" or "power" or both... So to me a "dark" append sadly isn't straight up the most logical step. And Internet co hasn't done a "dark" type as per say or a straight up one so it makes it less likely. :-/
