I actually had the same idea earlier today - a Battle of Britain-style map set in space. Funny.
But yes, it'd be a nice map. You could have optional targets such as UAV-style radar domes (like those atop Star Destroyers) that could be destroyed to make it harder for the defenders to react to waves of attack, and perhaps shield generators or deflection towers or something protecting a pair of the ships, or a section of the station? Then the primary objective would be to destroy containers and parked ships, as well as ships under construction. Defenders get cruisers, turrets, and fighters, attackers get various types of starfighters only. And perhaps a gunship or something. What kind of gunship the rebels have, though, I don't know. Perhaps an Assault Transport.
I'm reminded of the ending scene of Das Boot
.
"One of the bitches actually gave birth while she was attacking, and her puppies joined in on the carnage."
