is ther any reason why you couldnt install a rod at the extremity of the submain, and bond everything to that, including the CPC of the submain? this would then bring everything to the same potential, and negate the need for a new bonding conductor back to the origin?

No, the CPC would then become a bonding conductor.

I think the tables in this paper are far easier to determine compliance, as there are no further calculations to perform, unlike in the table above!!
