I agree that the first part was way better and that Light should've killed Near but be killed by Ryuuk after that. (I like your idea to make it look like Near is Kira).
But it was not really Near's plan. In fact it was Light's.
Sure, his plan in part one to kill L was way better (everything from losing his memories to letting Rem kill L and himself).
But his plan in part 2 was clever too.
Just like in part one he thought ahead a few steps.
He choose Mikami and knew that Near would easily find him.
Therefore he told Mikami to make a fake notebook even before Near found Mikami.
He knew that Near would follow Mikami. So he let him stage that scene in the train, where it seemed that Mikami used the notebook to execute a guy that attacked a girl.
He knew that Near would try to use Mikami to raise evidence against him.
And that he had to let Mikami appear at the warehouse to see their faces in order to do it.
All in all, that was a good plan.
The only thing I don't like is how it turned out.
Sure, we can say that he couldn't anticipate that Mello would kidnap that girl (although he did). But he didn't know that Mikami would act on that and lead Near to the real notebook.
But Light had to know that the real notebook was the Achilles heel of his plan.
That a person who thought of such a plan (not to mention the ones in part1) didn't have a backup plan is just ridiculous.
I've said it a few time already. Just tell Mikami to tear out a page of the notebook and always keep it close to his body, at the time he told him to make the fake notebook.
Since Near needs Mikami for his plan he can't arrest and search him.
That's a veeeeeery easy backup plan.
And if I can think of it, someone like Light should too.
