From a guy who has put up a few hundred dishes or so:
If you want to leave you 1000.2 up.and use a wing dish for 118.7, you can purchase a Dish Pro 500+ and just connect the F port to the input of a 1000.2 and you will get your end result. However you will have 2 dishes....
If you want to simplify the install, do as one person has suggested and set up a Dish Pro Plus 1000 plus (DPP1000+) and get all 4 with one dish....
EDIT: I did the math, more like a couple thousand dishes.
