Yes. I don’t think you need to change R1 as you probably wouldn’t hear any difference. You can use a 4PDT switch to wire the different components. You will need 4 poles to change the following:
1–D1, D2 cane change a pair of diodes from 1N34A TO 1N4148.
2– R3 change from 1M to 470K.
3–C5 change from 1u to 4u7.
4–C1 change from 1n to empty.
If 2 DPDT wiring boards will not fit side by side on a 4PDT switch, you may be able to use one of them on the switch.
I’m not sure if you will hear much of a difference in tone but that may depend on your other gear.
