You won't have the exact same DOF control, but Fuji's 16-50 2.8 seems to test and review very well. You may not even need to go with adapters
But to answer your question, I don't think Fuji has a Metabones (or any smart) adapter for Nikon. Assuming you have a newer 24-70 with no aperture ring, there wouldn't be any way to set aperture if you used it on a Fuji. This is not the case with Canon, which can AF and control aperture with a Metabones adapter.
Edit: I'm wrong:

But still, with how well the 16-50 is received you might have a more native solution if you went Fuji.
