Yeah, it's possible to do something like this as a fallback in XeTeX
font matching:

FT_ULong count = FT_Get_Sfnt_Name_Count(face);
for (FT_UInt j = 0; j < count; j++) {
    FT_SfntName sfnt_name;
    error = FT_Get_Sfnt_Name(face, j, &sfnt_name);
    if (!error && sfnt_name->name_id == 6) {
        char name_str[1024];
        memcpy(name_str, sfnt_name.string, sfnt_name.string_len);
        name_str[sfnt_name.string_len] = '\0';
        if (strcmp(ps_name1, name_str) == 0) {
            *index = i;
            break;
        }
    }
}

but xdvipdfmx still has trouble handling it.
