Ajax Ontario... okay, that's near Toronto, so you're pretty far east.
I'm so far west, I don't pay attention to the eastern-most satellites that -need- a Universal LNB.
And that's assuming you even want anything from them.
If you want to use a 4x4 or 5x5 multiswitch, I believe you'll need Standard LNBs, not Universal.
See the Switches Simplified FAQ for more discussion.
And if you're planning to run two motors from two receivers, that's not a well documented area of discussion.
Your intended layout isn't clear, but from the equipment you've mentioned, I see some clues.
edit:
One last thought.
There are a lot of motors manufactured with the generic SG2100 designation.
They're not all created equal.
I'd go for the STAB HH90, myself. In fact I did. -
