Following the ideas mentioned above about trimming the inside of the neck to get rid of the giraffe neck look, I tried something and it worked pretty well.
I popped open the neck joint and dremmeled the inside tabs that give the height of the ball socket. I wanted the joint to go deeper inside the neck, so using a dime (coin) I set a higher inside wall/tab that would limit how much more the socket and joint would go into the neck. I dremmeled new ridges where the sides of the coin would fit snuggly and then closed and glued back. No joints were cut off and the whole operation stayed inside the neck where you can't see it. Check out the pictures:

Subtle change but gives it a more natural appearance, especially in person!
***UPDATE
All right, I've made an improvement to my neck mod by adding a rubber "o" ring or rubber washer inside the neck to keep the rubber joint inside fitting even nicer and tighter. I also used a small strip of electrical tape around the inside neck joint as well. Check out the pictures of the mod done to Maglor's DX Batman neck:
There maybe ways to shift the compartment but I have not really paid attention to that lately
:I'm talking about this part....
My sonar neck is longer than my PERS neck. It seems really strange lol as if the neck needed to be any longer
It is longer and the you cannot shorten it using the above method as the battery compartment is right above the rubber socket
