Don’t think it would be that easy. What Yast does is creating a middle layer between the actual config files and the user. You can look at it, most (if not all) of it is stored in /etc/sysconfig. Yast generates the actual config files out of what is stored there. This can be a headache because editing the config files directly will sometimes lead to them just being overwritten bei Yast again.
This is probably the reason why other distros don’t even want to adopt Yast, it would have to fundamentally change how it interacts with the config files.
And the cool new thing is Cockpit anyway, even though it can do only a fraction of what Yast can last time I checked…
