I rarely tinker with rebel lists, but I felt like trying

Shoot Blount early...maybe after that he blocks....maybe dies...

Biggs doing Biggs stuff around corran...

Regeneration e wing....

Tried to use a Kyle Kagan hawk in there as support. Or...chAnge Blount ept to the one that soaks damage from a friendly just to buy Biggs another round of flying...

I would drop R5-P9 from Biggs for R4-D6, he normally won't have a focus after a round, if he's even alive. With those points, you could give Blount Assault Missles and put plasma torpedoes on corran.

I always struggle vs Tie swarms so +1 for Assault missiles.
