It looks like there's no hook that runs before gnus starts munging
buffers. So you'd probably want to advise the gnus command (before),
store (current-window-configuration) in a variable, and then as you say
add a hook to gnus-exit-gnus-hook that checks if there's a valid
window-config in that variable, and if so read it with
(set-window-configuration).

Hope that's useful,
