Yavin base. Could do with some love so I just waffled about this in another section but copied it here because this is where it really belongs.....
Rebel technician. Could even sell on the merits of a small vehicle if they made the cargo/personnel transporter sled. and should come with ground crew batons and cargo cases.
The Yavin base guard in the green uniform could have a removable helmet and have his peaked cap on underneath. would presumably come with rifle or whatever it is they carry. Maybe do a tri-head variants thing like they did with the fleet trooper.
Come to think of it a tri-head variation on rebel pilots would be cool too. especially if the pilots came with x-wing access ladders.
For Commander Willard they only need to re-use Captain Antilles' body. it's basically the same uniform. New head. Should come with the death star plans readout screen in a wall section.
Evram Lajaie can re-use Dodonas body. they wore the same. New head. Should come with the same tactical screen General Rieeken did.
Yavin base Communications officer. Re-use the yavin tech's body. New head. Should come with the large round display monitor that shows the Death star's proximity.
A Threepio and Artoo 2-pack would be cool. Threepio with knees and a hand able to hold a commlink. And Artoo DS battle damaged. Possibly have a plug in data cable so he can connect to the rebel computers.
Medal ceremony Leia should be an entirely new sculpt. the POTF ones were not up to much. and looked nothing like Carrie Fisher. Plus obligatory medals.
Luke, well he's rumoured to be on the horizon, Han VOTC would do here. And a decent Chewbacca.
Biggs, Wedge, Luke, Porkins, John 'Dutch' Vander, Theron Nett, Pops, Hutch, Tyree, would make an awesome boxed set. much like the bounty hunters box set.
And of course a re-release of the X-wing fighter with stickers for the wings where you can change the number of wing bars to get yourself different pilots' x-wing fighters. And the more of them you buy the bigger the squadron gets.
Could re-release Y-wing fighter I suppose. with the yellow nose markings but different dirtying paint apps and different blast marks. maybe darker rear engine parts and a completely different Astromech droid head. maybe an R5 unit.
