hm ...?

You mean like this?

(defun transpose-next-line ()
  (interactive)
  (let ((beg (point))
        (lin (line-number-at-pos) ))
    (beginning-of-line)
    (kill-line)
    (yank)
    (kill-line)
    (forward-line -1)
    (yank)
    (goto-char beg)
    (unless (= lin (line-number-at-pos))
      (goto-char (point-min))
      (forward-line (1- lin))
      (end-of-line) )))
(defalias 'tnl #'transpose-next-line) ; [1]
