There is no coincidence that back tilt/swing has been dropped in digital field view cameras. With tilt/swing in both front and back standard it becomes really tough to keep parallelism to the degree required for the short focal lengths used in digital when making wide angle shots.
There's a limit to how precise the zero dents on tilt swing can be, and if you have it both on front and back standard you get two sources of parallelism error. For product and closeup it doesn't matter, but for wide angle focused at a distance it does.
Therefore I'm a bit skeptical about the F-line being suitable for digital, but maybe it's okay. If you do go for a system primarily designed for analog your first thing to investigate is how parallelism will hold up for the wide angle shots. One test could be to focus at infinity shoot some test images of a detailed scene and look at the sides of the images and see if it's rendered equally sharp. With parallelism errors one side can be less sharp than the other.
