Yes, I <-> J interchangibility is frequent and i've been considering them to be an identical spelling. There are so many instances of both being used by the same scribe for the same words that considering them seperate letters is basically wrong for many centuries.
But this is what I was digging at. At the beginning of words Y makes more sense for replacing I/J when used as a consonant, like in dutch and german, but dutch and german continued using I/J as a consonant, not Y. English began using Y, in words such as "Yong" which turned into Young. I don't know if Y ever made a ʒ or dʒ sound.
What about "ij" at the beginning of words? Was that ever trialed by some folk at scale? Where the i makes a vowel sound, and the j is the consonant, (sort of) like in Partijen or Rijen.
Maij is a spelling I have seen, but ijuni or ijuli aren't something i've come across. I've only ever seen ij be used as it is today, with the sound of english "eye" or dutch "ei".
You do have ijs, ijzer in dutch.
