Sounds reasonable. It could be done by just reading the entire file contents after the shebang and re-writing them with the necessary offset all in RAM, truncating the file if necessary, without involving the zipfile module very much; the shebang could have some amount of padding by default; the file could just be re-compressed in memory depending on your appetite for complexity.

The biggest problem with that is finding the end of the prefix data. Frankly it's easier just to write a new prefix then use the zipfile module to rewrite all of the content. That's what the current code does writing to a new file.
