QMT for user taxonomies?

Hi!

How hard would it be to modify this plugin to be used on user taxonomies?
(https://www.ads-software.com/plugins/user-taxonomies/)
I love it, and I really want to have the same filtering functionality to be available for the user list of my site.

I can code… somewhat, but I want to know how much of the plugin would have to be modified for this to work. Is there anything that makes it near to impossible?
