An old lady and a Mon Cal pilot would have added nicely to that "The Rebellion is an equal opportunities employer" thing.
IMO, the old lady adds more to that "The Rebellion is underfunded and undermanned" thing.
Maybe that's precisely why it didn't make the final cut. There's a quote in The Making of ROTJ (I'll find it later) where someone asked GL if the uniforms and sets for the Rebel fleet shouldn't be more beaten up and distressed. Lucas answered that the Rebels actually had superior equipment compared to the Empire, and that's why they ended up winning the civil war.
