Boring won't increase displacement by much. However stroking will and it plays a bigger factor in overall engine displacement.
Look for posts by me with a bunch of math in the posts below:

I basicly prove that stroking increases engine displacement a lot more vs. boring.
As for your question about the crank. I don't know if one exists or not, or if you can use the crank from a 3MZ-FE.
