Maybe something utterly mundane and forgettable, like the Action IV transport,
Hmm. A little smaller than the Action VI, but not by that much. Still Silhouette 5, I’d say.
However, there’s not much information about it known at http://starwars.wikia.com/wiki/Action_IV_transport
or something FROM THE FUTURE like the Horizon-class yacht.
Hmm. That looks nice at http://starwars.wikia.com/wiki/Horizon-class_star_yacht
And close enough to the existing SoroSuub Luxury 3000 Space Yacht that it shouldn’t be too hard to do.
I'd say something like the Imperial Hunter, but seeing as you have nothing but a picture to work with, that just seems mean somehow.
Lots of room for exploration, though.
I figure a shotgun approach is a good choice. Maybe by randomly throwing stuff out there I'll hit something not taboo.
And I swear up and down I don't remember the Corona being so big.
Do you remember it being a replacement for the Nebulon-B? That would be a hint….
