I was trying to come up with an interesting twist for CC, and something dawned on me. Neither side of this war should have total control over what is available to them. Both the Empire and the Rebels are dealing with logistical issues. And this sets you up for some interesting scenarios and fleet builds.
The Rebels are scraping together whatever ships and fighters they can find. They are raiding boneyards to steal and resurrect old Y-Wings. Rebel supporters in the Empire are sneaking supplies to Rebel forces. Whatever funds they can put together are being spent on whatever ship or fighter they can find that is still spaceworthy. Hoping Rebel command could pull together a couple X-wings to fill out your fleet, but the only available stuff they could find was a scurgg and a Z95.
The Empire on the other hand has a much bigger supply of materials to select from, but with a large administration system, things don't run like a well oiled machine. You may put in a request for 4 TIE Defenders and get 8 TIE fighters instead. You may think you need an ISD, but central command believes that a Gladiator is good enough. You may really need a pair of Raiders, but due to heavy fighting in another part of the galaxy, the supplies of Raiders are all taken and instead they are going to give you a Victory instead.
All this variability forces the players to really have to adapt their build to the available ships/squadrons. And it would end in some interesting scenarios.
There is some flexibility in how you could do it also.
Shuffle the available ships, fighters, upgrades, etc into separate decks. If you want a small ship and have enough points for one, draw from the small ship pile. Want a turbolaser upgrade? Draw.
Another way would just be mix all the upgrades together, and all the ships together. Need a ship, draw until the first one you can afford. Same for upgrades. Want a turbolaser upgrade? Maybe you get a weapons team...better find a place to put that. Want an ISD, well you got a raider, but you have more points so draw again.
I see a lot of interesting drama unfolding. "I could really use an MC30 to add some punch to this fleet, but if I got a CR90, I could make that work. Heck, even a Hammerhead wouldn't be bad. Assault Pelta?! How am I going to make this work? Well, if I get AFF, I can make all these Scurggs a little quicker, or with EF I can add some flexibility to my ships. StM?! Come on!" Then he ends up winning the battle due to shield regen and the pelta becomes his fleet's mascot.
Yes, it would be VERY chaotic. And yes, it could be easily imbalanced if one side just pulls junk and never achieves any synergy of units while the other side is lucking out. But it would be fun and different.
