Corona Mix map defaults to perform mixing in sRGB space. If normal maps are supposed to be imported without gamma correction, should they not be mixed in sRGB space?

If your normal maps were already in sRGB, then they need to be loaded in with gamma correction, and then in linear space you can use Overlay.

If your normal maps are already linear, just import with no gamma correction, and Overlay in linear space.

I was under the impression that normal maps should be imported without gamma correction (2.2), and are therefore being imported as linear RGB?

It sounds like what you are saying is:
1. Perform mixing in whatever color space the texture is being read
2. Use the overlap blending option when mixing normal maps imported in the same color space

Mixing (overlay) should always happen in linear space.
