A Gungan, Wookie, Ewok pack would be interesting I think, since people draw parallels to those 3 in the films.
You know - I think this would be neat. I have always thought that Lucas wanted Jar Jar to be the "Chewbacca" of the PT.
I was thinking more about this recently simply because there is an absence of Jar Jar in the ROTS toy line.
Wouldn't it have been better if Lucas had scrapped any need for Jar Jar to be comic relief for TPM and instead have him be an exiled Gungan General who was banished for loosing a battle in the past? He could still have been saved by Qui-Gonn during the invasion, still owed him a life debt, still followed him to Tatooine, but during the final battle they could of had Tarpals die and then Jar Jar take over command of the Grand Gungan Army and defeat the Battledroids. Then in the rest of the PT, he could have still been Gungan rep to the Senate and when Yoda takes the clones to rescue the Jedi, he tags along and fights in the arena. Then during the Clone Wars themselves he serves as a Lieutenant under General Kenobi and in ROTS when Obi-Wan's clones turn on him, Jar Jar dies trying to protect Obi-Wan.
I think if GL had done something like that, I don't think people would MIND Jar Jar as much as a character. Instead GL had to make him a ridiculous clown and use that clown to practically ruin the first movie in the saga.
Yes, I think about Star Wars WAY too much...
