I like to think that Batman, though busted for having said plans, was thinking, “Wow. That worked a lot better than I thought it would. You guys suck.”
Bear in mind why many of those plans worked. Batman’s anti-Green-Lantern plan? Sneak into Green Lantern’s bedroom at night, when he’s not wearing his ring, and mess with him instead of shooting a bullet into his ear. His anti-Wonder-Woman plan? Shoot something into her ear. (Note to self: she’s really good at blocking.)
So you already have to be good enough to shoot GL and Wonder Woman in the ear; his plan doesn’t make it any easier to kill 'em, you handle that part on your own.
And if you have a regular-strength piece of kryptonite, I sure hope you can come up with a delivery system all by yourself – because Batman’s anti-Superman plan is to nerf a piece of kryptonite so it will nonlethally inconvenience the big guy, at which point you’re still at square one for springing the piece of kryptonite on him – which, if you could do that, what the heck do you need Batman or his plan for?
A similar question could be asked of many super hero teams. When they go to focus on the story of one character you can understand why the team wouldn’t be involved in the usual street crime or political corruption, but when the city’s about to blow up or an eldritch horror is rampaging across the Eastern seaboard you’d think the rest of the gang would take an interest. The story can ignore it, which leads to fridge logic, or it can come up with excuses, which after the 10th time seems contrived and awfully convenient.
I don’t know about the comics, but in the animated Justice League series they kinda nerf Superman so he isn’t the solution to all problems. Batman has the money, the technology, the industrial espionage, and tons of humint – he has contacts all over the world and a couple times he seduces low level female villains James Bond style. He often strikes out on his own to do the spy thing. He was the one unraveling conspiracies and enemy plans.
His inability to fly was played for laughs. He’d get annoyed when someone else would help him fight the low level bad guy army. It’s convenient he’s never shot in the big battles. A couple times he punches above his weight, like when he avoided Darkseid’s omega beams.
