Now a precedent has clearly been set, which comic characters, Canon or Legends

All of Zayne Carrick's entourage would be great, I simply love Jarael. And Lucien Draay also has his sidekicks too that should make a fine squad. On a sidenote it'd be great to have Squint as a Jedi before he becomes the dreaded Darth Malak.

We also already have Darth Talon, so the Sith under Krayt should also make way to the game eventually along with Cade Skywalker and others... Anyway, I don't think comics are a priority, but one may always dream...
