One would expect that if they were not envisioned like that before the movie premier, they are now. CB likes their pop-culture references and this one is world famous and designed to be sexy as an added bonus.
We know a bit about them, primarily from some of the RPG fluff. But I don't think we have any artist renditions, and only one rumors/speculation on what their rules will be. They are confirmed as a unit for Varuna, but whether they'll be available to Vanilla PanO also, or just Mercs that Varuna has access to... We'll have to see. Lots of people seem to think warband/direct template wielder, but there's also notions of mechanic transformation because their fluff says they wear pressure suits that keep them docile when they operate at surface pressure. I'm kind of excited at the idea of converting cube jaeger, krakot, and other legal mercs to all potentially be Helots.
