That'd be two of us plus AndyHalfElf who definetely go berserk if they killed Corran. Indeed, he could have been more important in NJO, but I have the feeling that Stackpole didn't want that many people messing with him, so he exiled him at the end of Ruin, there is his short appearance in EoV II, and later Star by Star and Allston's books, he wasn't that important for DW nor for Remnant. The thing is that he is much like Luke a Jedi of old, unlike Jaina and Jacen who represent the New Jedi Order, so I assume that on behalf of the editors they wouldn't put the antithesis of the New Jedi in the spotlight.
