Could try using get_footer() (not wp_footer() that's missing from a lot 
of themes), as all of the js effects scripts run "on dom loaded" and can 
be included just above the </body> tag. Then you could check for all 
scripts included in the header and all calls coming from templates and 
shortcodes.
