Oh, I thought the Bothan discussion was dead. I may try to wade through the pages of posts soon, but until then, here was my original concept for the Bothan sequence:

1. Bothan insertion into Coruscant via spacedrop (see my previous post)

2. Bousschchhch, already on Coruscant, provides them with a way in to the Imperial facility (again, see previous post)

3. Bothans sneak through facility, get plans, and are then discovered

4. Bothans attempt to escape, but are killed off one by one, until the final Bothan is picked up in mid-air by a Blockade Runner which surreptitiously leaves one of the skylanes, grabs the Bothan, and takes off for the sky at maximum speed (All those engines have got to count for something).

5. Boushh watches, intended as a backup plan, but gets into his ship and leaves once the Bothan has excaped. "Transmission incoming" reveals a photo/holo of the Falcon on Tatooine - Boushh jumps to hyperspace.

Regarding fur: Leave the Bothans fully helmeted and covered, but with strangely, unhuman shaped helmets (more snoutlike). Then, when one dies, their helmet comes off - The only Bothan we ever see is a dead one. This is much easier than having to have several actors in Bothan makeup, but shows us the expanding, less human nature of the Rebellion.
