Setting up the activities may get a bit complicated though with 3 TVs.

Another thought that I could possibly make work with a Harmony remote. Could use someone a little more knowledgeable confirming if this would be possible or not.
What about getting a MRF-350 base station from URC (or some other similar RF to IR hub with at least 2 emitter outputs) to receive the RF signals from the harmony remote, and then have IR emitters to go to each tv, but use IR over HDMI adapters to send the IR signal up the wall over a second HDMI cable that is already there and unused for each tv (since it isn't possible to get another cable fed up the wall. Then place the emitters over the IR receiver of each tv making sure it can't receive any additional IR signals (cover with electrical tape or something inconspicuous). OR can the harmony hub do that?
The base/hub would send out an IR signal to the other equipment like normal without an emitter since there is no confusion (cable boxes, blue ray player, and soundbar), and IR signals through IR over HDMI adapters to the emitters attached to the tv IR receiver. The main tv I could probably leave for the standard IR signal from the hub, just the side tv's through emitters to isolate them from the signal sent from the hub to only specific signals sent to each emitter.
Wouldnt' that work with the base station or possibly harmony hub?
The hub can send a general IR signal from itself, or signals to specific emitters and not other correct?
Would something else be necessary?
EDIT: Let me add, everything has line of sight in the room, and could work directly from the harmony remote or hub, just need to isolate the 2 side tvs from not receiving an IR signal that the middle tv receives. Plus the 3 xfinity x1 cable boxes may need isolation. They pair via RF to their xfinity r11 remotes with no cross talk, but not sure how that would work with a single harmony remote talking to multiple RF cable boxes individually
MRF-350 RF to IR base station:
IR over HDMI adapter:
Like this for the 2 side tv's, but the receiver dongle would be replaced with a cable from the hub to the module, and the emitter/sender would be placed over the IR receiver on the tv. So those tv's wouldn't receive the IR signals coming from the hub, but only the ones sent specifically to their IR emitter.
