Maybe a simpler solution is to change `fit-window-to-buffer'
so in such configurations when windows are split vertically
(the correct treating of horizontally split windows
is already provided in dired-pop-to-buffer you sent recently)
it will temporarily switch the current window to the upper window
and call `enlarge-window' from the upper window, thus resizing
the right border.
