Is there any way I can fix this? Am I missing something stunningly obvious?
SLIME is a minor mode and has its own keymap (slime-mode-map). C-c C-w C-w is bound in that keymap. local-set-key binds a key in the buffer's local map (lisp-mode-map). When Emacs looks up a key, it first looks in the minor mode map and doesn't see your binding.
You can either use a different key, say C-c w w, or bind it in the slime-mode-map, with (define-key slime-mode-map ...).
