This works for me. Could you, please, tell which emacs-version and
tramp-version you are using? I'm a little bit surprised by the "Cannot
connect to different host" error message, this sounds like Tramp
2.0. You need Tramp 2.1 for the recipe I gave you.

This shall work with the settings above.

For this, you need another rule, like

(add-to-list 'tramp-default-proxies-alist
              '(nil "\\`different_user_to_my_local_user\\'" "/ssh:%h:"))
