Anyway, to go with three satellites, you would have to have a SW64, or convert ALL the LNBFs to DishPro - and that probably can't be done with the Winegard unit.
So, pick 2 of your units for 110 & 119, grab the 2 outputs of each along with 2 SW-21's, slam it all together and you should be good.
NOTE: it's very likely you're going to have big trouble with the 921 if you do NOT aim the 110 dish - unless you disconnect the un-aimed one and run Check Switch every time it's nt aimed. And then of course, reconnect and run Check Switch when you DO bring in the 110 bird.
I wonder if you could get a LEGACY Quad, give it's #1 feed to the aiming unit, and then take 2 of it's other feeds for the 921. It's a long shot, but maybe it'll work. Why not call Winegard and see what they have to say about 2-tuner units. Wait a minute - didn't I say that somewhere already?
