taxonomy cloud checkboxes

I thought about an admin en-/disabling functionality to add checkboxes to the /tagadelic-list like this snippet:

function theme_tagadelic_weighted($terms) {
  $output .= '<form action="/tagadelic/submit/">';
  foreach ($terms as $term) {
    $output .= '<input type="checkbox" name="term" value="'.$term->tid.'" />'.l($term->name, taxonomy_term_path($term), array('class'=>"tagadelic level$term->weight")) ." \n";
  }
  $output .= '<input type="submit" value="Submit" />';
  return $output;
}

, which should (on submit) list the selected terms, e.g. /taxonomy/term/26,21,5.

I hope you like this idea, if not: then not.
