From your explanation, could "yi1 yu3 shuang1 wen2" be actually "yin1 yu3 shuang1 wen2" (音语双文) ? When one uses both "yin1" (音, sound) and "yu3" (语, language or words) together to write Chinese, one uses both Hanzi and Hanyu Pinyin. This fulfills what you mentioned: "you3 yong4 Hanzi, you3 yong4 Hanyu Pinyin, 有用汉字, 有用汉语拼音).
