I am not sure whether this feature is of real interest or we got nothing better to discuss... But for what it worth this is how i see it:
* You want smaller and cheaper passenger component for short intra system flights. Currently, there is no way todo it without making Cryo obsolete. Otherwise, you'd need to find away to restrict its usefulness by time.
* Such component makes most sense on extremely short fights, while Aurora turns can extend as far 30days. For which Cryo chambers are far more efficient as they require non of the living quarter necessities, just stack them high.
* Thus your are either going to be forced to crawl or have your fast passenger shuttlets parked in orbit ~29 days out 30. And create some special rules.
* If civs were to use it, this will increase traffic requirements, which the opposite of the direction I observed in latest versions. You'd to update their creation\AI code, deal with pathfinding, which would be limited by their cargo range, and you'd need to make sure your intra-system liners don't become stranded in your home system. Also loading unloading order might need to be updated.. etc
So yeah, I don't think you can fit well within the scope of Aurora mechanics, nor that such a limited use feature worth Steves time. We already have Cryo chambers for either long term colonization operations or basic low-cost fares; And Luxury cambers for those seeking comfort like private sleeping cabins, minibars, sexy flight attendants, and entertainment. I am going to use my imagination\GM to fill in the rest.
