Do you have a budget for this project yet?
I have done this quite a few times in large theaters with multiple screen or multi function rooms for commercial applications, but it can get expensive to do it correctly. The fact that you are only trying to do 5.1 makes it a lot cheaper (can probably be done for about the same price if not less than buying (2) AVRs, HDMI DAs to split all of your video sources, and a custom speaker selector).
Here is the system break down.
- All video inputs would feed an a AV pre-amp or receiver with (2) routable HDMI Outputs (something like a Yamaha RX-A1060).
- 5.1 audio pre amp outputs would feed the inputs of an 8x12 DSP. (Something like an Ashly Audio ne24.24m can be found on eBay for $600-1000 depending on I/O count). You would need 10 outputs if you include 2 sub outputs and processed them as well through the DSP, or if you wanted to save some money you can just deal with the L,C,R,SL,SR in the DSP and let the AVR drive the sub(s) directly and you would only need 8 outputs.
- The 8 outputs of the DSP would feed 8 channels of amplification than would feed the 8 individual speakers in the room.
In the DSP you would have (2) presets that can be recalled based on the listening position of the room.
For controlling the entire thing you can get a fancy as you want with it. For the Ashly in particular, there is a button on the front of the device, an iPad app, or you can use a third party control system for the preset recall.
I built a 3 position 7.1 system a couple years back using this method (got quite expensive when you get the DSP I/O count up), but at the end of the day the client walked into the room and with the push of a button the system would configure it to the way they wanted to use the room for the day.
I can put together some basic system drawings to show you the signal flow if you end up going this route.
