Rebels and...Vehicle Force?

In the fourth season finale, the Galra decimated a third of the rebel forces. How many friends has Matt lost in his year and a half in space? Could this lend him some back story and development?

At the end of the episode, we see five rebel ships remaining. Each ship carries three rebels. Basic math, five times three is fifteen, giving us the exact number of the eighties Vehicle Force team. Not saying they'll form their own Voltron, but it could be an interesting homage. Even if we just got an episode or two devoted entirely to the rebels, I would be soooo happy!
