I've briefly looked at the filters. Yes, it seems like that might be one
way to do this. But I have a hunch it is already implemented, and that I
just don't know how to access it or what variable to set.

See:
http://orgmode.org/cgit.cgi/org-mode.git/tree/lisp/ox-latex.el#n2280

Where Case 1 is no fontification, Case 3 is minted, and Case 2 is
custom. I can see that if `custom-env` is set correctly, it wraps the
code exactly as I want above:

       (custom-env (format "\\begin{%s}\n%s\\end{%s}\n"
                           custom-env
                           (org-export-format-code-default src-block info)
                           custom-env))

But I'm not sure where to set custom-env, although I know I want to set
it to `pyconsole`.

  -k.
