Traveller to DS2/SG2

I'm trying to adapt the Tickets from Mercenary and 76 Patrons to DS2 and SG2,
and I was wondering if anyone had some general guidlines to the populations of
the colony worlds in the GZG background. (Or would anyone want to give
Traveller stats for GZG worlds!).

For Tech I am assuming the Major powers are @ Tech 12 (IMHO the most difficult
Tech to design in) and Minor powers and colonies adjusted accordingly.

I welcome any thoughts/info/currency that you send my way.
