I don't mind the references to the NEC, I just wanted to know about circuitry than code in this particular question and just wanted to be clear what my question was (very difficult to express in a bulletin board sometimes, thanks sparky!)
I tend to agree with you as the "best" location to make the GEC connection in this particular service arrangement. Also, I think it is better because if one panel is being worked on, the GEC isn't temporarily lost for even a short period of time for the rest of the working system. I know where the code requires the connection, but I may propose a local amendment for this particular arrangement of service that the GEC be made at the largest set of SE conductors.
Our utility (Com Ed, recently aquired by Exelon) does not oppose as of yet, ground connections in the meter socket. And there are manufacturer installed terminals to do just that. Com Ed does require the metersockets to be stamped CECHA approved.
