Probably against a Doom Shuttle or a Shuttle+Fettigator squad...

Would this be viable?

Luke Skywalker + Draw Their Fire + Engine Upgrade + R2-D2 (37)

Biggs Darklighter + R2-F2 + Shield Upgrade (32)

Blue Squadron Pilot + Fire-Control System + Heavy Laser Cannon (31)

Look fun anyways. Biggs keeps Blue and Luke out of arms for a bit. When Luke is getting some hurt he goes back to Biggs. And Blue pewpews from a distance with his HLC...
