Let me do a little research, I already have an EX580 II and 2 EX430 II's, I know that your 600RT will serve as a master for all of them, I am not so sure that I have use for the Yongnuo's but I am also not familiar with their capabilities. I need to read about your controller also. Will it fire the Canon flashes?
Yes .... it will fire both Canon and Yongnuo with full control over the units, even the 'zoom' feature. I would use the Canons for on-camera and in my hand. Used the Yongnuo's for the lighting that would be on light stands. The reasoning was if someone knocked over a light stand I wanted it to be the cheaper Yongnuo's.
As you can control the speed lights from the Canon menus I seldom used the controller, used a 600 as the master and changed the programs via the camera menu which is easy to do. I decided I wanted the 'fill' flash on-camera so the controller was seldom used.
