I really wish a new A-Wing Pilot would come out and that they'd then re-issue the A-WIng fighter using this new sculpt pilot and perhaps a new head. I awnt a Blue McQuarrie A-Wing though... That's one I'd gladly buy up multiples of once more.
I have 4 greens and over 6 red ones. I love the A-Wing.
I'd take a repaint of the EU Airspeeder as well. It was concept art that got adapted for the RPG's... I don't expect to see it ever released again, but if it were I'd dig seeing it with a new paintjob, maybe something spiffy and colorful or camo'd... Just something unique and new, not from the films.
And if we're including beasts, I'd be all for a Bantha with a new rider and a Dewback with a new Sandtrooper...
