All you need to do is disconnect the wires from the top end of the volume control (including the capacitor that's connected there) and connect the Bluetooth module to the now empty tag, with the return lead to chassis. And for dual-purpose use, have your changeover switch do it.
There may be some breakthrough of radio, at a low level - if so, you'll need to silence the radio circuitry. One way would be to open-circuit the HT supply to the IF and frequency changer stages (purists would say leave a small bleed with a 47k 1W resistor so that the valves don't suffer by being operated with zero current flowing).
