Any particular reason not to have three nodes which are acting both as master and slaves?
None at all. I'm not a cluster or networking guru, and have only played with mesos in cloud-based settings so I wasn't sure how this would work. But it makes sense, that way the 'standby' masters are still participating in the zookeeper quorum while still being available to do real work as slave nodes.
