(defun swap-windows ()
  (interactive)
  (let ((buffer (current-buffer)))
    (other-window 1)
    (switch-to-buffer-other-window (current-buffer))
    (other-window 1)
    (switch-to-buffer buffer) ))

I think that works by itself but if not the whole source is ...

;; same window for new things
(setq display-buffer-alist '((".*" display-buffer-same-window)))

(defun beginning-of-line-at-top ()
  "Position point at `beginning-of-line'.
Then put that line at the top of the window."
  (beginning-of-line)
  (recenter 0) )

(defun doodle-buffer ()
  (interactive)
  (let ((doodle-buffer "~/ooa/doodle.el"))
    (if (one-window-p)
        (progn
          (split-window-below)
          (other-window 1)
          (find-file doodle-buffer) )
      (find-file doodle-buffer) )))

;; the two-window solution

(defun other-window-or-split ()
  (interactive)
  (when (one-window-p)
    (split-window-below) )
  (other-window 1) )

(defun swap-windows ()
  (interactive)
  (let ((buffer (current-buffer)))
    (other-window 1)
    (switch-to-buffer-other-window (current-buffer))
    (other-window 1)
    (switch-to-buffer buffer) ))

;; window size shorthands

(defun window-increase-size (lines)
  (interactive "p")
  (window-resize nil lines) ) ; the current WINDOW

(defun window-decrease-size (lines)
  (interactive "p")
  (window-resize nil (* -1 lines) ))

(provide 'window-incal)
