I once thought he should be set-up as a permanent rival entity to Batman with his own base, methods, followers, similar to Talia and the League. And I've always thought he'd be a good match to Poison Ivy too, not in a strictly romantic way but more as friends and allies. I'd have to see where the current stories finish up though who knows what will happen. The idea of him partnering with Damien is pretty cool.
When he was Robin...I wouldn't change a thing, except retroactively introduce some more adventures where he was actually useful and admirable as Robin, e.g. The Cult. There aren't enough notable Jason as Robin adventures where he is a) exhibiting some distinct character, b) shown as a force to be reckoned with and c) shown as a vulnerable young kid, and an essentially good kid, who needs saving from himself. They really only made him interesting in the year leading up to his death, particularly in the last few months
What he needs is a miniseries that adds new Robin adventures, fixes his return from the death (no more reality punch) and establishes a new direction as a top tier Batman rogue and occasional ally. Also since his return he's yet to interact with Drake or Grayson in a satisfying way, and there's so much you could do there, things that DON'T involve him turning into an octopus. Also it was SUPERMAN that convinced Batman not to hunt down the Joker, when Batman was positively murderous. Let's see Jason VS Superman, he is smart and angry enough to make a decent attack on him. Also Iran.
