I don't know whether this will help you or not but you can try this, For the title of the expose filter result you can try to add in between Global: Result summary or Global: Text area from add header and the expose filter call the views_exposed_form on result use the

    function mymodule_form_alter(&$form, &$form_state, $form_id) {
    
    if ($form_id=='views_exposed_form')
    {
   
 $form['#submit'][] = 'call_ur_form_state_function';
    }   
    }

function call_ur_form_state_function($form, &$form_state){
//dpm($form_state);
}

to alter the $form_state value, there you will get the all array and object of the current view to alter, by this way probably you can reconstruct your string for output page.
