But would you have aliens at the Hoth or Yavin bases?

When you look at those rebel troops in their trenches on Hoth it feels like a real battle, WWII with lasers.

Would it feel the same if some of those guys had tentacular faces?

It could still feel like a real battle. Only on a galaxy far, far away... I get your point though, but we shouldn't ignore the setting. Wookiees would fit great on Hoth.

ROTJ definitely needs more aliens in the Alliance. Not just Mon Calamari and Sullustans,

Oh, right. Forgot the Sullustan.
