The prototype of the mysqli_stmt constructor is mysqli_stmt::__construct(mysqli $link, $query);

To extend mysqli_stmt, do

class myStmt extends mysqli_stmt {
  public function __construct($link, $query) {
    parent::__construct($link, $query);
  }
}

class myI extends mysqli {
  public function prepare($query) {
    return new myStmt($this, $query);
  }
}
