I had Dish Latino Max and I upgraded to the HD package and a 622 last month. The CSR told me, sure it will be $20.00 for the HD package. This month I got my bill and there is no more Dish Latino Max, it was changed to the AT250 Package + HD package + Dish Latino Package making it more like $38.00 more.
So like Yes616 said, no he'll need to get one of the other packages and add the Dish Latino which is $12.49 if you have AT100.
