[Esperanto orthography] provides the option to either choose x-digraphs, h-digraphs or caron diacritics (i.e. circumflex on consonants and breve on vowels) and there are some alternative proposals, e.g. substituting 'ŭ' by unused 'w'. No naturally evolved orthography, as far as I know, mixes consonant and vowel letters in digraphs, but 'j' and 'w' or 'v' can be both and 'h' is a special case. Using 'x' after consonants and 'w' after vowels would therefore make some sense, although it still looks strange to people used to natural graphotactics. Readability may be improved if not all diacritics are put above the base letter.
