I think this would be of great use. The FCB is based on the Softrock DDS
design, which evolved to a family of different solutions, with the
common factor of a stereo sound interface and a HID interface for
control like frequency, source multiplexer switch and filter banks.
AFAIK the HID commands are the same in most of these designs. Treating
the system as a single interface much like a USRP would get users rid of
extra programs and doing things every time over again.

Well, implementing it as UHD device seems a bit overkill from a programming point of view because one would have to implement the "audio source", which is readily available in GNU Radio. So a GNU Radio source just like the old pre-UHD USRP drivers seems to be most feasible.
I don't know much about the Softrock series, but I doubt they have much in common with the FCD. Maybe the USB idea and the protocol structure, which for the FCD is really trivial and simple streams of 1-4 bytes per command. Most of the commands and parameters for the FCD map directly to the tuner chip, which I assume is not present in the Softrocks - see attached screenshot of the windows controller.
