It may just be who holds this sentiment, I don't know, but I still simply don't like the idea of semblances that target nervous systems working on Grimm because we simply don't know if it can be done. If Emerald shows her hallucination semblance working on them, then fair enough I'll be a bit more open to it, but until then I can't really support it.

As for replacing the functions by adding more effects against humans, that's up to you. I don't really think it needs to be done if you don't wish to.
