It already does that.

If you have index.cgi, it will be called for directories.

Relevant httpd.c part:

#if ENABLE_FEATURE_HTTPD_CGI
        else if (urlp[-1] == '/') {
                /* It's a dir URL and there is no index.html
                 * Try cgi-bin/index.cgi */
                if (access("/cgi-bin/index.cgi"+1, X_OK) == 0) {
                        urlp[0] = '\0';
                        g_query = urlcopy;
                        send_cgi_and_exit("/cgi-bin/index.cgi", prequest, length, cookie, content_type);
                }
        }
#endif

and networking/httpd_indexcgi.c is a C example of such CGI.
