I think he may go back to the Yoda early years thing, but from a fans point of view i'd love him to cover storys from all the bounty hunters (Dengar,Zukass,4-Lom,Bossk,IG88,Boba Fett,and even Mara Jade, and Jango).
There's a back story where the inventor of IG88 built 9 Robots and was killed upon activation of the droids, then for some reason were hell bent on killing Boba Fett (i never read the comics as to why if it was covered in there). Bossk had limbs that would instantly re-grow if severed. Dengar was brain damaged and unable to feel pain.
It could also add credibility to Jango's high reputation that is apparently evident yet unfounded in Attack Of The Clones.
