Sorry, I hit send before finishing, this works:

#+BEGIN_SRC emacs-lisp
  (defvar your-extended-keymap (make-sparse-keymap))
  (define-key your-extended-keymap (kbd "o") 'your-other-window)
  (defun your-other-window ()
    (interactive)
    (other-window 1)
    (set-transient-map your-extended-keymap)) 
  (global-set-key (kbd "C-x o") 'your-other-window) 
#+END_SRC

But as Tassilo said, you probably do not want this. Check 
ace-window (https://github.com/abo-abo/ace-window) which solves 
both scenarios very elegantly.

Best,
