I like many of these ideas, mostly the Zeppelin and flying free in WW1 arena. That could be quite the teaser for newbies to get into the action of WW2. (Side note, what about letting people fly free in the DA?)
If a Zeppelin is created I would think it should have some gunner positions manning little .303s. I know Zeppelins had them in real life, not sure how many.
