*puts on orthographic history glasses* 👓 but Lady, considering the history of germanic umlaut, don’t you run the risk of the superscript E being further reducᵉd to a simplᵉ diacritic? lik̈ this, for exampl̈?

*takes off glasses* but you see, dieresis on the preceding consonant is already the function silent E is performing

anyway i’m just saying setting a letter in superscript is a transparent way of encoding additional meaning without making things difficult to read for existing speakers
