You can't stop nano from opening any files that you give it, but you
can prevent 'less' from calling nano directly.  You could set the
environment variable EDITOR or VISUAL or LESSEDIT (see man less) to
the name of a script, and let this little script check the size of
the file and from this size let it decide whether to open it or to
print "No no".

Cheers,
