Howdy miconexrsgs,
That’s a cool modification. You are certainly on the right track. There is one thing to keep in mind though, the WP theme/template is the outer region that surrounds the content. The Organizer override that you made is for the content itself, it can not override the outter template.
Usually when people want to do something custom on a specific page, they just use one page template. However, they add their special stuff inside of PHP conditionals like:
if(tribe_is_event_organizer()) { //do magic }
If you do not like that method you could attempt to override the template itself for the organizer page. You would need to tap into the WP filter template include, with a priority of 11 or more.
Does that all make sense? Does it fully answer your questions?
