If those third-party additions are using
  (define-key ctl-x-4-map (kbd "z") 'foo)
rather than
  (global-set-key (kbd "C-x 4 z") 'foo)
then I think you can handle it, by changing ctl-x-4-prefix and
ctl-x-5-prefix to functions that temporarily add ctl-x-4-map or
ctl-x-5-map as a minor-mode keymap and then read a key sequence.

And if they are using global-set-key, then I think it can be
hacked around by doing
  (put 'ctl-x-4-prefix 'define-key-keymap ctl-x-4-map)
  (put 'ctl-x-5-prefix 'define-key-keymap ctl-x-5-map)
and changing define-key to follow the define-key-keymap property
if the keymap contains a symbol whose function definition is a
function and the key sequence didn't end yet.
