That's pretty much how I imagine launches from the hanger are conducted. If the mainhall were to be remodelled, it should include the "runway" or strip, like you say, and maybe part of the fore section of the Orion's main hull too, assuming the viewpoint is kept the same.
I remember a thread about ship landing gear that diverged into a discussion about how this "mainhall" does not represent the Orion's hangar, because the runway and main hull section are not shown - you'd probably just see the hull from that viewpoint. Furthermore the two Hercs outside the hangar/mainhall look as though they are on a collision course for the main hull section. I see these as just inconsistencies though, and that what we're looking at is supposed to be the actual hangar. But you could take an alternative view and suggest that it's a ship maintenance area with a large multi-functional screen used for announcements from the bridge or something, and that when it's in "standby mode" it shows a view of the outside.
Anyway, a remodelled mainhall sounds like a nice idea.
