With the changes Adywan make to the introduction of the Death Star scene, the Falcon vs. Tie battle, and the battle of Yavin IV, I think the guy is more than capable of adding a few rebel transports and a few one man ships (like X-wings and Y-wings) getting taken out on and above Hoth.
Yes, ESB is near perfect. However, one has to admit that it looks like a total of five or six rebels die in the battle.
It just isn't realistic. IMO, Adywan definitely seems to want consistency, continuity and dare I say it, a sense of realism.
I base this on his stellar work on ANH. If changes beyond the basics aren't made here, all that was for naught.
