Meetings are a poor indicator of continuous integration. Instead, build a steel thread. Make the simplest thing that can go through every team first. Every team working on the project goes to build that initial slice of functionality. When done, you have the infrastructure and tests necessary to make sure each next slice is functioning. It means that you have a low level friction through the project, but it is much smaller than the overall friction at an integration phase. Then, use meetings to discuss the clarification of the specification and the technical design. Any status meetings can be at the EM/PM/Lead level as necessary but you will have the feedback to know how things are progressing quickly.
