Force action conversion

I am sorry if this is in the wrong forum thread I don't know where this should go. I have an Anakin Skywalker force action lightsaber and want to convert the soundboard to a NB or a PT and if I can I want to upgrade the LED. I don't know if this is possible but what I am planning to do is replace the board with a NB, keep the switch, buy another switch for the auxiliary. I will post a few pictures after Christmas because I will be gone visiting family.

Edit: Ok I tried to do it but I could only fit in the NB but not the luxeon led.
