Not without recompiling PulseAudio, the relevant code is in 
src/pulsecore/protocol_native.c, function command_auth:

#ifdef HAVE_CREDS
     if (do_shm) {
         /* Only enable SHM if both sides are owned by the same
          * user. This is a security measure because otherwise data
          * private to the user might leak. */

         const pa_creds *creds;
         if (!(creds = pa_pdispatch_creds(pd)) || getuid() != creds->uid)
             do_shm = false;
     }
#endif

Maybe there's more stuff that needs to be changed as well, I don't know.
