I think Gnus mechanism is irrelevant to doc-view.  Gnus uses mailcap
mechanisms to find the appropriate mailcap entry and run an external
program in a separate process.  doc-view displays the rendered image
in the Emacs buffer.  So it could work exactly as image-mode for
pdf/ps/dvi files.

As for the mailcap feature, I recall there was a proposal to put
programs from the mailcap entry to the default value of the ! command
(`dired-do-shell-command').
