If it is OK to "simply" split windows maybe this is less complicated to
install:

(defun tn-split-window-signature-on-top (&optional numlines)
  "Split window at point leaving minimum 2 lines of defun beginning on top"
  (interactive "p")
  (let ((start-pos (point))
        (start-line (line-number-at-pos))
        (toplines (if (> numlines 1) numlines 2)))
    (beginning-of-defun)
    (split-window-below (1+ toplines))
    (window-resize nil (- toplines (window-body-height)))
    (recenter 0)
    (other-window 1)
    (goto-char start-pos)
    (recenter 0)))

Should work with any function understood as a defun. You can control how
much of the beginning of the defun to show with a numeric prefix
argument (like C-u). I find it comfortable that point will remain on its
current position in the lower window (at the moment you forgot about
arguments).
