This depends on what kind of signal is required.

Thiago stated that you can get the present available names on the bus by 
running.

If this suits your needs, a new signal with no other parameters would 
suffice, telling that the configuration has been reloaded.

In that case an additional section in the spec like 
https://gitlab.freedesktop.org/dbus/dbus/-/blob/master/doc/dbus-specification.xml#L6378 
would do it.

The new implementation needs to be added to bus_context_reload_config() 
(see https://gitlab.freedesktop.org/dbus/dbus/-/blob/master/bus/bus.c#L1079)

As example for constructing and sending a signal, see 
https://gitlab.freedesktop.org/dbus/dbus/-/blob/master/bus/driver.c#L340
