For 1. and 3.:
Cambo and Arca have Canon lens boards with electronic aperture control for their bellow cameras. They don't require the collaboration with Fuji. The main problem for those devices is the small difference between the flange distance of Canon EF (44mm) and Fuji GFX (26,7mm). It results in only 17.3mm space. That brings the lens panels quite close to the camera and its grip. I am very interested in such a solution. So to check out if it would work I took product photos and scaled them to the same size in photoshop, using sensor size, mount diameters and mm-scales on the images as references. I think it is quite exact. My results:
a) the Arca F-Universalis lens board with aperture control will fit with the camera in landscape orientation. But the grip will limit the horizontal shift to one side to next to nothing (remember there is also the bellows between lens board and the grip which I didn’t draw). You could compensate that with the shift on the lens, but it’s a bit strange to do that on a view camera. Arca would probably have to make a dedicated bellow with a wider opening for the larger sensor, and a new mounting ring for the Fuji. Portrait orientation won’t work at all, because the lens board is about 12mm higher than wide, it collides with the grip.
b) the Cambo Actus lens board for Canon with aperture control is much narrower. It will fit in landscape orientation with enough space for shift in all directions. Cambo would probably have to make a new bellow with a wider opening. Their rotating mount for the camera side would have to be replaced by a thinner on without rotation - it is too thick to fit in the 17.3mm together with the lens board. In portrait orientation it won’t fit at all, much too high.
c) Cambo has a Canon lens board without aperture control for the Actus. This is much smaller and will work in both camera orientations with enough space for shifting in all directions. But no aperture control (set aperture on a Canon camera, detach, mount on the Actus, no easy switching between working aperture and full open).
So it looks like there will be no easy solution. Someone will have to develop a product further or from the ground on. I very much hope that someone would chime in and do that. A fixed adapter with aperture control by metabones would be a great thing. Or a shift adapter like a mini-pancake-camera with interchangeable panels for different MF-lenses.

1.
will the gfx open their system to use it on viewcameras like the cambo actus? with the x1d it is not possible as i know...
2.
hope that we can edit fujifiles in c1
3.
we can use third party lens like the canon tse
