Might work a bit, but no. Speices could not talk like they're supposed to and don't get me started on Wookies.

Yes rw would interfere with the RP aspect with different alien language like the language of the wookies. But for combat it would be useful and as long as everybody can speak basic then maybe it could be used for just combat?
Rp your character was meant ot be separate. I was referring to having a voice channel open so the PA could communicate such as sharing information. If a PA has challenge everyone to a dual then people on the voice server could help out. If you find a good mining spot or a new unexplored area you could share it with the group. If people are looking for a group then an announcement could be made. This could be used in conjuction with a PA chat channel over the game. Yet it may be better because if someone its getting chased by a krayt dragon and needs fellow PA's to help then the chat channel on the game would be more difficult to use than simply pressing the intercom voice communications button.
