I was thinking the same thing but Noel posted somewhere, that for right now, it's optimized for vocal range. Hopefully they will continue development to make it more general purpose. Would love to be able to tighten up harmony guitar leads for example.
Correct me if I'm wrong, but if it covers the complete vocal range from bass to soprano, wouldn't it cover almost every note on a guitar as well? If it's optimized for voice, there's only one note (low E) that isn't covered. And frankly, I think the bakers would have done a bit of overlap, just to be sure.
So, what you have in mind should be possible.
I found this chart which shows how the ranges of various instruments, including voice, overlap:
