Well he did outsmart Mr. Myxylplyx and stole his powers, turning the world into his own grotesque image, killing Batman numerous time at that point in the "Emperor Joker" storyarc. Yeah sure he may have lost his powers in the end of the story arc, but he was "victorious" at that point in time before losing his powers.

Let's also take in account the "Last Laugh" story arc where he Jokerized an entire prison full of metahumans under his control and started a nation-wide killing spree, which caused Lex Luthor as president to start a war with him.

Also let's take into account where he stole a Nuclear Warhead and almost sold it to terrorists, better yet almost killed all of the world's leaders in the UN building had it been not intervened by Superman in "A Death in The Family."

So yeah he is capable of doing grander schemes.
