I spent several months when T20 first arrived creating and entering data for Campaign Suite using the Modern d20 as the template base. Unfortunately I quit trying to do it when so many inconsistencies within CS began to appear. I found many of the Traveller idiosyncracies did not translate well, in particular trying to get Lifeblood and Stamina to calculate correctly. Entering the skills and equipment was simply just time consuming but getting the career terms and generating careers and characters automatically proved beyond my computing skills. Unfortunately I have since moved on from CS and no longer have any files. I did try with Metacreator which is far more adaptable but harder to write the code for.
Sorry if that was rather negative and not much help, but I hope you don't have to waste as many hours as I did.
