Once you have summed all the tuner outputs into the IF, I don't see how
you are going to unscramble the analog signals at the IF output.
It can be done with spread spectrum, digital signals by using one receiver
and a number of correlators. In fact this is the basis of a very important
patent that made small, many channel GPS sets possible.
