Well, if you want more kludges...  You could replace the "xv %s" with a
call to a script which checks whether $DISPLAY is set; if so, does "xv
%s", otherwise dialogues with you about saving the image.  You still
wait for the download (the dialog comes after rather than before the
download), and you don't get to not-download it, but it's a step.

Changing Lynx to actually allow X to be "toggled" is certainly possible.
It's a small-to-medium project, as Lynx projects go.

Easy to kludge, medium difficulty to fix properly.  You are encouraged
to dig into the code and fix it properly.  ;-}
