Good to see this being considered, but so far this is one anomalous week.
For the time being, it would be fine for an XO to command an additional ship borrowing another XO as his 2IC. That gives other junior officers the opportunity to XO and it dilutes the cadets into environments where they can get a good idea of the expectations and behaviours of a seasoned TSN crew. That immersion is what Inculcates good habits. Having too many cadets together does not let them see how amazing a crew can be. We see this all the time with local cadet forces. They do mot have the example of how to be awesome.
