You can do stuff like that by overriding the new parameters in my fork at https://github.com/ses4j/TinyMCE

s_textmetrics_template: function (ed, t) { 
    return '<span>Using <span id="' + t.ccid + '">0</span> of a max 500 characters.</span>'; 
},
s_textmetrics_updater: function (t,d,m) {
    if (t.ccid > 500) d.setHTML(t.ccid, "<span style='color:red'>" + characterCount + "</span>");
    else d.setHTML(t.ccid, m.characterCount);
},
