Even if such adapter existed, you wouldn't be able to use native Fujifilm lenses.
On native Fuji lenses, the focus ring and the aperture ring are not mechanical, but electronic. Yes, turning those change the aperture and the focus when you have a camera connected. But try turning these with the lens detached from the body, or with the body turned off, and nothing will happen.
That means that if you don't have 1) electricity and 2) a software to communicate commands to the lens, you won't be able to use the lens. And Fuji doesn't provide a public API, so unless ZWO does like Viltrox and retro-engineers the whole connectivity to the camera...
The only lenses you could actually use are non-Fujifilm lenses with an X mount. Like, Samyang lenses in Fuji X mount, because they are completely manual. But then again, you'll run into problems with flange distance.
A Fuji lens has a flange distance of 17.7mm, which is very close to the flange distance of cameras like the ASI2600 (17.5mm). So, for these cameras, you can't create a 2mm adapter. Which means, only the smaller ZWO cameras could be used potentially (the smaller ones like ASI1600MM-Pro, or the planetary ones like the ASI178). On these cameras, you have about 11mm to play with, which is enough for making an adapter.
So I don't think ZWO can do anything about it, sadly... Which is pity, Fuji lenses are really superb!
