I don't think so.  The relevant code portions are in
gnu/services/sound.scm and read among others:

  (define pulseaudio-environment
      (($ <pulseaudio-configuration> client-conf daemon-conf 
     `(("PULSE_CONFIG" . ,(apply mixed-text-file "daemon.conf"
                                 "default-script-file = " 
                                 default-script-file "\n"
                                 (map pulseaudio-conf-entry 
       ("PULSE_CLIENTCONFIG" . ,(apply mixed-text-file "client.conf"
                                       (map pulseaudio-conf-entry 

Due to a bug with webkit sandboxing, we no longer put daemon.conf into
/etc/pulse (my bad), but rather set PULSE_CONFIG to directly point to
it.  As you can see, `default-script-file' should be set to the file
you're supplying.  I am currently unsure, at which point this variable
gets updated (I still think you need to reboot), but I'm pretty
convinced, this would work with a custom script file.
