It's a nice idea and all, and who ever wants to believe that the meld is the reason for his reaction, go for it. However, I still think you're reading too much into it. Picard has a great respect for Kirk. Look at the exchange from Unification:
SPOCK
I was involved with... "cowboy
diplomacy", as you describe it,
Captain, long before you were
born.
PICARD
Nevertheless, sir, I am not
prepared to leave until your
affairs are completed.
SPOCK
(beat)
In your own way, you are as
stubborn as another Captain of
the Enterprise I once knew.
PICARD
Then, sir, I am in good company.
Now he is standing face to face with this legend, and this legend has basically said 'welcome to the club'. Of course Picard has got to be thinking 'this is pretty cool'.

Kirk was only picky about which junior officers called him Jim. That was reserved for close friends. Throughout TOS and the movies, his senior officers often called him Jim. Now consider the fact that Kirk is coming to the understanding he has been in the Nexus for nearly 80 years and that he is meeting the newest Captain of the newest Enterprise, and that they are about to take on a life or death mission together. "Call me Jim", would be far from out of character.
