I don't recommend doing that but it should be possible with so called
"around-advices". The idea is that your "advice" code runs instead of
the original function and then you can decide to call the original
function according to some condition (if (called-interactively-p) ...).
See the Emacs Lisp manual and section 17 Advising Emacs Lisp Functions.

But I'd just choose a different name for such user-interface sort
command and perhaps bind it to a key if it's needed often.
