In a more "conventional" campaign, I'd love to try a Gl'lu. The combination of adventurous, overly cautious, and indifferent to disaster sounds like it would be fun to portray, and physically they're fun too.
More off-the-wall, my user name comes from a semi-serious idea for a campaign I'd love to try some time, in which players are members of a Girug'kagh film crew producing a series of smug "reality television" in which silly foreigners get their comeuppance for not knowing their place. That is, following a K'kree warband in a region in the process of being "civilized", and gleefully chasing the action to get footage of misfortune as rogue ham-sandwich-munchers get trampled.
Or, a related idea, a general celebration of the "henchman" races. The backdrop being a big conference somewhere in Crucis Margin between Imperial, Solomani, Hiver, and K'kree interests... and the players are a bunch of Bwaps, Dolphins, Ithklur/Gurvin and Girug'kagh rushing around underfoot doing all the "lesser" work and pursuing their own interests in between the demands of the bosses.
