it may be possible, but it would take quite a bit of testing just to figure if it is or not. I would start by adding a filter on that hook and somehow figure out to see what is in the value $form_field and then go from there.
// this added to the filter will output the contents of $form_fields
// to your error log so you can inspect it
ob_start(); print_r($form_fields); error_log(ob_get_clean());
