yes of course but make sure you put the Diseqc Switch between the motor and the Dishes. I mean the RG-6 coming from the FTA STB goes directly to the motor and then from the motor you go to the 4 port DiseqC switch. An then all 4 Dish go to 1 port in the switch. Then do the proper config in the STB menu to tell it which Dish goes to which port. It is in fact apparently a very common setup at least combining a fixed dish with a motorized one because it will allow you to change channels to your favorite fixed dish quicly and then only the "move to dish" delay for the rest of the satellites. I am assuming that you have 3 fixed dish and only 1 with a motor. 2 motors from the same box eventhough not impossible at list makes no sense. Of course I have not done it myself therefore I could be wrong but I am hardly ever wrong lol lol lol lol. Enjoy fast changing channels back to your 3 fixed sats then lol lol lol. Ah! I almost forgot, you are very welcome.
