Taxonomy browser check boxes?

Hi, I'm using the patched 5.x version Taxonomy Browser (http://drupal.org/node/115890), which works great. But the taxonomy selection is made by multi-select elements. I'd like to change that into checkboxes. Is that possible? I looked at modules like Taxonomy super select and Formtweaker, which do exactly what I want, but they only work for node adding/editing, not for taxonomy browsing.
Thanks for any suggestions!
