You don't get a new Emoji by creating a change .org petition lol
You need to write a proper proposal and send it to the Unicode consortium: https://unicode.org/emoji/proposals.html. If it gets rejected, it's four years until you can reapply for the same Emoji.
Yeah I doubt it'd be approved... I was just saying that there's an actual process that has to be followed. The Unicode consortium aren't going to care about a Change .org partition that gets maybe 20k signatures at most given billions of people use Unicode and they've got proper processes to go through.
