Custom Icon Picker Shortcode In Shortcode Ultimate Plugin

Hi Folks,
I’ve been working on building some custom shortcode for Ultimate Shortcode plugin.
I’ve managed to create some shortcodes already.

The API (http://gndev.info/kb/shortcodes-ultimate-api-overview/) allows to have select, text, color and bool as fields.
I wonder if anyone tried to integrate font awesome icon picker as a field in the plugin.

Thanks in advance.
