It seems simpler than what that younger-than-I whippersnapper thought:
;; - 's' in *Groups* (to save the newsrc).
;; - Launch other instance:
M-& emacs -Q --daemon=fetcher --load=.gnus.el -e "gnus-child"
;; (If you want to fetch from a server that you're reading, unplug, mark
;; what you want downloaded and 'M-g' (in Summary, to update),
;; beforehand. Then add '-fetch-session' to the 'emacsclient' below.
(set-process-sentinel
(start-process "emacsclient" "*fetcher*" "emacsclient" "-s"
"fetcher" "-e" "(gnus-group-save-newsrc)" "(server-edit)")
(lambda (process event)
(princ (format "Process: %s had the event '%s'" process event))))
M-: (gnus-parent-read-child-newsrc) RET
Unplug ('J j') [1] for any servers updated while you were plugged (close
the server, just to be sure). Then '/ N' or 'M-g' (Summary).
Ta-da!

1: I've a patch for nnatom for unplugged operation, which... is
cumbersome to reach atm (let me see). nnrss as well, but that's trivial.
