Streaming from two remote locations with x2 encoder?

I want to stream to Facebook Live from two remote locations with two x2’s to a Facebook Page. It would need to be a split screen. This may not be possible but would like some input from others about doing this. I have looked into creating an rtmp server but would have to have a powerful pc to lug around and would need an hardwired ethernet connection. I may be dreaming but would appreciate some input. Thanks Carroll
