That's a good idea. Add the Mandalorians as a reputation faction and give out the long sought after blue Mandalorian armour and a title.
I'd love that! Seriously, I want the blue Mando armor, whether Cartel Coins or otherwise, and I'd grind dailies for a year if I had to in order to get it myself! And not to mention enough credits to buy it for me, Torian, Mako, and Akaavi! I'd enjoy doing dailies for the Mandalorians, especially if I got the gear and the title; shoot, just the gear.
