This is a non-trivial task, and not simply because people will refuse to change their habits as they always do.
You say that “busy” should be “bizy”, but are you sure about that? If we decide that Y should always have an “ee” sound, what do you do with words that start with Y? Or are we going to make it the rule that it always has a Y sound at the beginning of a word and an ee sound at the end? What about a word like “ripe”? That’s a different-sounding I than the one you have in “bizy”, so would that be “ryp”? In that case, you have to have 3 pronunciations for Y: one each for when it occurs at the beginning, ending, and inside a word.
