You can do that with display tables. Current buffer's display table is
in variable "buffer-display-table". It has a slot that controls how
invisible text is displayed. Perhaps this is does what you want:

    (add-hook 'gnus-summary-mode 'my-gnus-summary-mode-hook)

    (defun my-gnus-summary-mode-hook ()
      (set-display-table-slot buffer-display-table 'selective-display [?…]))

You see, there is a vector [?…] which sets the character(s). Three Ascii
dots would be [?. ?. ?.]. See info node "(elisp) Display Tables".
