I suppose I also assume someone with Android ROM development experience is better positioned to take up organizing such a project as an overall smaller effort, there by being faster and more efficient. Other real life constraints also seem to suggest not pursuing this type of thing in lieu of other things I should be pursuing and already procrastinate. But, here there be dragons, or at the very least a can of worms.
I'll bet there is already a manufacturer whose TVs can all communicate intratelevisually (non-standard proprietary frequencies) – and then, if even one of them is online... they're all relaying within their private intra-TV spyware meshnets to their various relays.

In unrelated news, my 2012 Sony Bravia is still fantastic, even if not for (4K) high-refresh games (the image quality remains fantastic for casual usage).
