One difficulty would be that positions are byte offsets from the begining of the book text and mobi and azw3 have different lengths because of differences in formatting.

It's easy for automation to deal with that -- look up the position in the first book, capture some text (sans formatting) around the position, look for that text in the second book starting at the same position (since it is probably somewhere *near* there, even if not actually there), use the new position if found. If not found, just use the position unchanged (and warn) because it's better than losing the note.
(Have I done it? No, but I've written similar tools for different very non-ebook-like formats which do just this, and it works.)
