I'm creating a circuit to switch and control between two different analog signals, and I'm doing so with JFETs and a CD4013. If I'm using a guitar pedal stomp switch to pull up or down the data line, can I use a pull-up resistor in this configuration to mimic an SPDT switch?

Yes, your design using a pullup resistor should work fine. It will draw a little more current from the battery when the button is pressed, but it's less than a milliampere and should be negligible.
Sometimes you have to worry about switch contact "bounce" but since your switch data goes through a flip-flop that latches the switch signal, this should not be an issue. Good luck!
