OK, so how about this?

- does not use the kill ring

- point remains in the same (textual) line, at the
  same column

- move forward or backward (with lines, e.g., -1 to
  move backward one line)

- move forward or backward any number of lines (with
  lines by any number of lines)

- set up keys and aliases as fit...

(defun move-line (&optional lines)
  (interactive "*p")
  (let ((lin (line-number-at-pos))
        (col (current-column))
        (num-lines (or lines 1)) )
    (beginning-of-line)
    (let ((line (thing-at-point 'line)))
      (delete-region (point-at-bol) (point-at-eol))
      (delete-char 1)
      (goto-char (point-min))
      (forward-line (+ lin num-lines -1))
      (insert line)
      (forward-line -1)
      (beginning-of-line)
      (forward-char col) )))
(defalias 'ml #'move-line)
