That's apparently not how glyphless-char-display works. The docstring
is a bit ambiguous, but glyphless-char-display actually *defines* the
characters that cannot be displayed in an ordinary way. For instance,
if you do (aset glyphless-char-display ?a 'empty-box), that tells Emacs
that "a" is a glyphless character, and causes all "a"'s to be displayed
as empty boxes.
What you are thinking of is a char table that says "how should we
display character C if it has no font", but AFAICT there is currently no
such facility. There is only the extra slot of glyphless-char-display,
which handles all characters with no font without discriminating.
