it should work, extremely POORLY, but if you want the spanish channels, the dish upgrade should be free, and shouldnt take more than a few minutes depending on how many receivers you have and how difficult it would be to run two new lines off the dish if needed. it could be as simple as taking the old dish off and putting the new dish on, or you may need a new install if you have 3x4s all over the place... or a 4x8 / 6x8, then you need another 2 lines run from the dish to the switch..
