How would I switch between either of my two outputs into one input?
You’re circuit is working but not the way you planned on it to work. It’s working because you’ve directly connected all those Pins at CRT port to respective pins of OUT port. You essentially bypassed the PNP transistors. Also this PNP switch won’t operate properly like this and it’s not best suited for this application. I recommend using an analog switch IC as this is what it can be used for. In your case you want to switch pins from one input port to either PORT A or to PORT B for example. To accomplish this task, you can use a Quad SPDT analog switch such as the ADG333A from Analog Devices. Here you can wire an input port to pins D1 through D4, output port A to pins S1A through S4A, and output port B to pins S1B to S4B. IN1 through IN4 are control pins.  

I should mention that if you use this IC, it requires power sequencing if use dual supply(ie, power to  positive power first then power to negative supply.) But you can also use different but similar functioning IC.
