Unfortunately, no, I don't think that's going to be possible.
We did a similar transition in src:policykit-1, but we found that usermod
will refuse to change the home directory of a user that is currently
running any processes.
I'm CCing the adduser maintainer(s), as this seems to be an
interesting use/edge-case.
Note that usermod is part of passwd (a lower layer than adduser), not
part of adduser.
If I understand correctly, most of the options we pass to adduser only
set its behaviour if it creates our user: if our user already existed,
adduser does not alter it.
We don't currently use sysusers.d in the dbus packaging, but if we did, I
believe it would behave similarly to adduser: if the messagebus user
needed to be created, it would be created with a specified home
directory, but if it already existed, systemd-sysusers would not alter it.
