I think you'll probably get your wish dazzz, for a little while at least;

Gaara we will never see again, mark my words, his arc is over, he learnt his lesson and he went home. It would just be cheesy and rehased if he made another appearance.

Hinata might be on the sidelines every now and then for one panel, but as for doing missions or actual combat, I doubt it, she's just too weak compared to other characters to be worth it.

It was said about Shino that he is currently on a mission with his dad. A slightly poor excuse for the fact that Kishimoto has nothing for him to do, so it'll probably be a while before we see him again.
