You can use the --format option to send requests for different itags. You can of course kill youtube-dl at any time and start another download. I'm not sure what you mean by switch them during download. Could you elaborate?

As a command-line application, you can only communicate with youtube-dl with signals. Simply kill it and restart it with another format.
