Three LG TVs on one Wall - Flirc setup?

Hoping that this is OK to ask here.  I've been researching a problem that we've been having, and some other websites have pointed me here as a potential option.  Here's my setup:

Two LG UR9000, one LG C4 - all one one wall together.  The dream was for me and my two sons to be able to play minecraft (via xboxes) or other games (via playstations/nintendos) together on the TVs.  I also have an Nvidia Shield Pro connected to each - in the event that I'd like to game and watch two things on the other TVs.

I read in advance of buying the TVs that you could disconnect the LG remotes and then reconnect them to separate the signals - but I've tried pretty much everything I've read, and it's not working as intended.

Here's what I'd love to do.

Option 1 - control each tv with it's own remote (LG or Flirc) - without having to use apps on phone/tablet to power them on.

Option 2 - control each tv with one remote - with profiles set up to power on and control each TV (not sure if possible).

The key is I also need my wife and sons to be able to easily turn them on/off/switch inputs.

Would some combination of the Flirc USBs/Remotes help solve this?  I'm willing to spend money to solve the problem if it means buying new remotes or a new piece of hardware.
