I think it would also help to expand -iu to -iou and -ui to -uei, and of course u->ü where applicable. IMEs could still accept both forms. Pinyin is pretty well-adapted for entering Chinese, but I think that goal is at odds with being easy to pronounce. I'm not sure that having one ISO standard for both purposes is a good idea, although if China ever starts to export more culture, maybe everyone will eventually learn how to pronounce Hanyu Pinyin.
