No, you cannot move a sink input to a source. Sink inputs are Output Streams and Sources are input devices. A monitor source is just a device that you can record from (just like a mic). It will contain the same data that is playing on the device. > In addition, if a Bluetooth HSP sink is connected to 2 sink input > streams, how does the bluetooth sink handle different audio formats > such as sampling frequency?

As said on the other thread, it should be resampled and then mixed. That's certainly how other sinks work and I don't think the bluetooth one is any different (but I don't know the code that well).
