I dont know what speed you need, but what about using a pair of arduinos and multiplexing the data over two channels?

Eg, use one channel for the switch number and the other channel for on/off. The arduino on the Tx side can cycle through the channels and the Arduino on the reciever can demultiplex them.

If your radio lets you mix from the trainer channels then you can make up a simple switch board and then just plug it in.
