I'd rather pick another key shortcut that is not used currently. As I
commented in another thread, such a shortcut is useful even in the
no-split-view case where it could set focus on the view, independent on
where focus was before. Not sure what the best shortcut would be though.

Ctrl-Tab?

10.2.4.2. Standard Widget Navigation Shortcut Keys in
http://library.gnome.org/devel/hig-book/stable/input-keyboard.html.en 
lists some interesting keys, like:

F6, Shift+F6 - Give focus to next/previous pane in a GtkPaned window
F8 - Give focus to splitter bar in paned window

Maybe we could use F4 or something for switching between views /
focusing the view.
