Not really.

They were two different people, just read the early posts in bitcointalk.

There are just way too many messages, even at different time zones and they show different personalities.

It would be a colossal waste of time for SN, and he was known for exactly the opposite. He even released Bitcoin with the most liberal license because he said that using any other more restrictive one would just lead to some people replicating it and basically duplicating work.

Hal just happened to be in the right place at the right time to meet SN.

SN remains anonymous because he is a smart person and made sure to have privacy all the time. I mean, these guys are expert cryptographers, not a random dude.
